Description
Dicalcium phosphate 0AQ is an inorganic phosphate salt with the chemical formula CaHPO₄. It occurs as a white, odorless, crystalline powder that is poorly soluble in water. This substance is also known as dibasic calcium phosphate and is commercially offered in a so-called “0AQ” form, meaning the product is free of crystal water (anhydrous). Dicalcium phosphate is widely used in various industries, including Food Industry, Pharmaceuticals, Agriculture and Animal Nutrition.
