Dicalcium phosphate anhydrous is a calcium phosphate compound with the formula CaHPO₄. It appears as a white, odorless powder and is commonly used as a dietary supplement, food additive, and pharmaceutical excipient.
🏭⚗️ Production
Dicalcium phosphate anhydrous is typically produced by reacting calcium carbonate with phosphoric acid, followed by drying to remove water and obtain the anhydrous form.
🔬 Properties
It is a white, tasteless, and odorless powder that is practically insoluble in water but soluble in dilute acids. The anhydrous form is more stable and has lower moisture content compared to its dihydrate counterpart.
🧪 Applications
• Food industry: Used as a nutritional supplement and leavening agent in baked goods.
• Pharmaceuticals: Commonly used as a binder and filler in tablets and capsules.
• Animal feed: Added as a calcium and phosphorus supplement for livestock.
• Dental care: Occasionally used in toothpaste as a polishing agent and source of calcium.
