Calcium Phosphate
Ca₃(PO₄)₂ / CaHPO₄ / Ca(H₂PO₄)₂ | CAS: 7758-87-4 | HS: 28352600
Product Description
Calcium Phosphates are a family of calcium salts of phosphoric acid encompassing three primary commercial forms: Monocalcium Phosphate (MCP, Ca(H₂PO₄)₂), Dicalcium Phosphate (DCP, CaHPO₄), and Tricalcium Phosphate (TCP, Ca₃(PO₄)₂). MCP is the fastest-acting leavening acid in baking powder and self-rising flour, reacting with baking soda at room temperature to release CO₂. DCP is the most widely used calcium and phosphorus supplement in animal feed formulations and pharmaceutical tablet diluents and excipients. TCP (food grade E341iii) serves as an anti-caking agent in powdered foods and as a mineral supplement. MITCHEM supplies all three forms with appropriate analytical documentation for each application sector.
Applications by Industry
Monocalcium Phosphate is the primary fast-acting leavening acid in baking powder, self-rising flour, and pancake mixes; reacts with NaHCO₃ to release CO₂ for lift during mixing and baking.
Dicalcium Phosphate (18–19% P) is the most economical source of bioavailable phosphorus and calcium in poultry, swine, cattle, and aquaculture feed — essential for bone mineralisation and growth.
DCP is used as a tablet diluent, direct compression filler, and calcium supplement in pharmaceutical dosage forms; TCP is used as a disintegrant and anti-adherent in solid dosage forms.
Tricalcium Phosphate (E341iii) prevents caking in powdered foods, table salt, and spice blends; also used as a mineral calcium supplement in fortified foods, beverages, and dietary supplements.
