Application

Calcium phosphate, a calcium salt of phosphoric acid, is a versatile compound with a wide array of applications due to its abundance in nature. It serves as the principal mineral for producing phosphate fertilizers and various phosphorus compounds. A significant form, tribasic calcium phosphate (Ca3(PO4)2), is a key inorganic component of bone ash and is widely used across multiple industries. In agriculture, it enhances soil fertility as a plant food. In manufacturing, it stabilizes plastics, while in the pharmaceutical sector, it is a staple in dental products and bone replacement transplants, thanks to its similarity to bone minerals. Calcium phosphate also acts as an anticaking agent, stabilizer, and nutrient supplement in animal feeds. Furthermore, it plays an essential role in mitigating exposure to radionuclides such as strontium and radium by blocking their absorption in the gastrointestinal tract, thereby showcasing its significance in health and nutrition.
