Application

Calcium phosphate, AR, with a purity of 96.0%, serves a versatile and crucial role across multiple industries due to its chemical properties and natural abundance. It is primarily a calcium salt of phosphoric acid, essential for producing phosphate fertilizers and a variety of phosphorus compounds. With its presence as a principal inorganic constituent of bone ash, calcium phosphate finds application in medical fields as a component in bone grafts, thanks to its similarity to natural bone minerals. In agriculture, it is utilized as a fertilizer supplement and serves as a nutrient for animal feed. Moreover, calcium phosphate proves beneficial in manufacturing, being integral to glass production and dental products. Its unique ability to counteract strontium and radium radionuclides highlights its application in health and safety measures, where it competes in the gastrointestinal tract to block the absorption of these radionuclides, thereby reducing their impact.
