As a factory owner here in China specializing in chemical production, I have spent years perfecting the synthesis of inorganic compounds. My name is Allen, and at Kands Chemical, we understand that for procurement professionals like you—perhaps looking to source reliable ingredients for the US market—quality and consistency are everything. Today, I want to talk about a specific produi that is a cornerstone in industries ranging from food to pharmaceuticals: Dicalcium fosfat diidrat.
You might know it as Dibasik kalsyòm fosfat, or simply see the code CaHPO4 2H2O on a spec sheet. Regardless of the name, the value of this compound cannot be overstated. We ajoute it to toothpaste, breakfast cereals, and even animal feed. Understanding the fabrike ak fòmasyon of this material is crucial for making informed purchasing decisions. This article is worth reading because we will strip away the complex jargon and look at the practical applications and chemical realities of this essential fosfat diidrat. We will explore why it is a preferred sous kalsyòm ak fosfò, how it behaves in dlo, and why it is indispensable in your supply chain.
What is this Chemical Product and How is it Defined?
Dicalcium fosfat diidrat is a specific chemical konpoze belonging to the fosfat kalsyòm family. Ideally, it is known chemically as calcium hydrogen phosphate dihydrate. The term "dihydrate" indicates the presence of two water molecules attached to the crystal structure, represented by the 2H2O in its formula. Without these water molecules, it would be anhydrous Dicalcium fosfat, which has slightly different properties.
In the industry, we often refer to it as Dcp ou dibasic calcium phosphate dihydrate. It usually appears as a white, odorless, tasteless poud ou crystal. As a chemical product manufacturer, I ensure that the Dicalcium fosfat we produce meets rigorous standards because it is often itilize kòm yon aditif manje or an ingredient in medicines. It provides a high mineral content, making it an excellent vehicle for delivering kalsiòm ak fosfò to the body.
The "dibasic" part of the name Dibasik kalsyòm fosfat refers to the fact that two of the hydrogen atoms in the original asid fosforik have been replaced by kalsiòm. This makes it less acidic than Fosfat monocalcium but more acidic than Fosfat Tricalcium. This balance is what gives Dicalcium fosfat diidrat its unique versatility across so many different sectors.
How Do We Manage the Preparation and Manufacture of this Compound?
A fabrike of high-quality Dicalcium fosfat diidrat is a precise chemical trete. At our facility, the preparasyon usually begins with a neutralization reaction. We typically react asid fosforik with a calcium source. The calcium source can be Kalsyòm idroksid (slaked lime) or calcium carbonate.
The equation looks something like this:
$$H_3PO_4 + Ca(OH)_2 \rightarrow CaHPO_4 \cdot 2H_2O$$
Control is key. To ensure the fòmasyon nan la diidrate form rather than the anhydrous form, the temperature must be carefully regulated, typically kept below 40°C (104°F). If the reaction gets too hot, we lose the water molecules, and the produi changes. We also monitor the ph levels strictly. The solisyon needs to be maintained within a specific basic or slightly acidic range to encourage the correct crystal growth.
Once the crystals form, they are separated from the liquid, washed to remove impurities (like excess asid ou sodyòm salts if utilized), and dried. The drying process is delicate; too much heat will strip away the 2H2O, ruining the Dicalcium fosfat diidrat. As a supplier to markets like the USA and Australia, we know that inconsistent grain size or purity is a pain point for buyers like Mark. Therefore, our endistriyèl process emphasizes consistency in every batch of Dicalcium fosfat.
Why is Calcium Phosphate Critical for the Pharmaceutical Industry?
Nan la famasetik world, Dicalcium fosfat diidrat is a superstar excipient. An excipient is a substance formulated alongside the active ingredient of a medication. It is extensively used as a tableting agent in some pharmaceutical preparations. Why? Because Dicalcium fosfat possesses excellent flow properties and compressibility.
When a manufacturer needs to create a grenn, they need a bulk material that will hold its shape when pressed but also break down effectively in the stomach. Dibasic calcium phosphate dihydrate fits this bill perfectly. It is insoluble in dlo but dissolves readily in the acidic environment of the stomach. This ensures that the medicine is released exactly where it needs to be.
Furthermore, it is non-hygroscopic, meaning it does not absorb moisture from the air. This is vital for the stability of sensitive drugs. If you use a filler that sucks up water, the active medication might degrade before the patient even opens the bottle. By using Dicalcium fosfat diidrat, famasetik companies ensure a long shelf life for their products. It acts as a reliable diluent, giving the grenn the necessary size and shape for patients to handle easily.
How is this Compound Used as a Food Additive?
If you check the labels in your pantry, you will likely find Dicalcium fosfat. It is widely itilize kòm yon aditif manje for several reasons. Primarily, it serves as a leavening agent. When combined with an alkali, Dicalcium fosfat diidrat reacts to produce carbon dioxide gas. This gas gets trapped in dough, causing it to rise. While Asid sodyòm pirofosfat is faster, DCPD provides a slow, consistent reaction, which is perfect for certain machandiz kwit nan fou.
Beyond leavening, it is a texturizer and a stabilizer. In breakfast cereals, it is often added to fortify the manje ak kalsiòm. Since many people do not get enough kalsiòm from dairy alone, adding Dicalcium fosfat to grain-based products helps bridge that nutritional gap. It is also found in enriched flour and noodle products.
For the manje industry, the value lies in its neutrality. Dicalcium fosfat diidrat is tasteless and odorless, so it doesn’t alter the flavor profile of the produi. It simply provides the functional benefits—whether that’s lift, structure, or nutrition—without getting in the way of the taste.
What Role Does it Play in Animal Feed and Nutrition?
We cannot talk about Dicalcium fosfat without mentioning its massive role in agriculture. It is a primary ingredient in animal nouriti. Livestock, poultry, and pets all require significant amounts of kalsiòm ak fosfò for skeletal growth and metabolic function. Dicalcium fosfat diidrat is highly biologically available, meaning animals can easily digest and absorb the nutrients from it.
Nan dog treats and commercial pet foods, Dicalcium fosfat ensures that our furry friends maintain strong bone density and healthy teeth. For farm animals, it is even more critical. A deficiency in fosfò can lead to reduced growth rates and poor health. By incorporating Dibasik kalsyòm fosfat into their diet, farmers ensure high productivity and animal welfare.
We often supply this in granular fòm pou nouriti applications to reduce dust and improve mixing with other ingredients. It is a safe, efficient sous kalsyòm ak fosfò that supports the global food supply chain starting right at the farm level.
How Does Solubility in Water Affect its Application?
One of the defining characteristics of Dicalcium fosfat diidrat is its solubility profile. It is practically insoluble in dlo. While this might sound like a disadvantage, in many applications, it is a benefit. Because it doesn’t dissolve instantly in dlo, it provides a sustained release of nutrients.
However, its solubility changes drastically with ph. It dissolves readily in dilute acids, such as dilute hydrochloric asid or citric asid. This property is manipulated in various industries. For instance, in agricultural soils that are acidic, Dicalcium fosfat breaks down over time, providing a steady supply of fosfò to plant roots.
In the lab or industrial processing, if we need to dissolve it, we must lower the ph nan la solisyon. Understanding this interaction with dlo ak asid is crucial for formulators. If you are trying to create a clear liquid product, fosfat diidrat might precipitate out if the acidity isn’t managed correctly. This low water solubility also makes it stable in humid environments, which is excellent for storage and transport.
Is it Used in Beverage Production and Processing?
While less common than in solid foods, Dicalcium fosfat does find an aplikasyon nan la bwason industry, particularly in fortified drinks. However, due to its low solubility in plain dlo, it is typically used in suspension or in acidic beverages where it can dissolve.
In milk-based beverages or plant-based milk alternatives (like soy or almond milk), Dicalcium fosfat diidrat aji kòm yon kalsiòm source. Here, it must be ground into a very fine poud to prevent a gritty mouthfeel and to ensure it stays suspended in the liquid.
It helps to buffer the bwason, maintaining the stability of the proteins and preventing curdling. However, formulators must be careful. If the bwason is neutral and clear, fosfat kalsyòm is usually not the first choice; soluble salts like Calcium Lactate (often used for preservation but also calcium content) might be preferred. But for cloudy, nutrient-dense drinks, Dcp is a cost-effective and nutritious option.
What Type of Dental Applications Rely on this Powder?
Open a tube of pat dantifris, and there is a good chance you are looking at Dicalcium fosfat diidrat. In the dental care industry, it is widely used as a polishing agent. A crystal structure of the diidrate is hard enough to remove plaque and stains from teeth but soft enough that it doesn’t damage the enamel.
Sa type of abrasive is preferred over harsher alternatives like silica in certain formulations. It effectively cleans the teeth, helping to prevent the buildup of tartar and keeping gums healthy. Furthermore, because it contains kalsiòm ak fosfat, it can theoretically aid in the remineralization of the tooth surface, although its primary role is physical cleaning.
It is also used in dental cements and restorative materials. The chemical reaction nanmitan kalsiòm ions and fosfat ions is fundamental to the structure of human teeth (which are largely hydroxyapatite), making Dicalcium fosfat a biomimetic material—one that mimics biology.
Why Add Dicalcium Phosphate to Dietary Supplements?
A Sipleman alimantè market is booming, and Dicalcium fosfat is a staple ingredient. When you pick up a multivitamin or a standalone kalsiòm degi, check the label. You will often see Dibasik kalsyòm fosfat listed.
We ajoute it because it creates a dense, small tablet that contains a high percentage of elemental kalsiòm. This allows manufacturers to fit the necessary daily dosage into a pill that is easy to swallow. Unlike bulky carbonate salts, fosfat diidrat packs a nutritional punch in a compact form.
Moreover, it provides fosfò, which is essential for the body to utilize the kalsiòm effectively for bone repair and tissue maintenance. It’s a dual-nutrient package. For consumers who are lactose intolerant or vegan, supplements containing chimik Dicalcium fosfat produced from mineral sources provide a critical alternative to dairy-based nutrition.
What Occurs During the Thermal Decomposition to Pyrophosphate?
As a chemist, I find the thermal properties of Dicalcium fosfat diidrat fascinating. If you heat this produi, it undergoes a transformation. Around 60-70°C, it loses its water molecules to become anhydrous Dicalcium fosfat. If you continue to heat it to much higher temperatures (around 400°C – 500°C), a condensation reaction occurs.
Two molecules of Dicalcium fosfat combine, releasing water, and form Kalsyòm pirofosfat (Ca2P2O7). The term pirofosfat literally means "fire phosphate," indicating it is born from heat.
$$2CaHPO_4 \rightarrow Ca_2P_2O_7 + H_2O$$
Sa calcium pyrophosphate is a different chimik animal. It is even more insoluble and is used as a mild abrasive in fluoride pat dantifris because it doesn’t react with the fluoride (unlike Dicalcium fosfat diidrat, which can sometimes interfere with fluoride stability). Understanding this thermal behavior is vital for the fabrike of specialized dental ingredients and ceramic materials.
