Kalciumfosfaat

Kalciumfosfaat is a general term referring to calcium salts of phosphoric acid. These compounds are ubiquitous in nature and play crucial roles in biological systems and various industrial applications. The most common form is hydroxyapatite, which is the primary mineral component of bones and teeth in vertebrates. Its chemical formula is Ca5(PO4)3(OH). Other important forms include dicalcium phosphate (CaHPO4) and tricalcium phosphate (Ca3(PO4)2).

In the human body, calcium phosphate is essential for skeletal integrity, muscle function, nerve transmission, and blood clotting. Dietary intake of calcium and phosphate is vital for maintaining these functions. In agriculture, calcium phosphates are used as fertilizers to provide phosphorus to plants, which is a key nutrient for growth.

Industrially, calcium phosphates find applications in a wide range of products. They are used as food additives, serving as anticaking agents, leavening agents, and nutrient supplements in processed foods, dairy products, and beverages. In toothpaste, they act as abrasives and remineralizing agents. The pharmaceutical industry utilizes them in tablet manufacturing as binders and fillers. They are also employed in ceramics, paints, and as bioceramics for medical implants due to their biocompatibility. The specific properties and uses of calcium phosphate vary depending on its exact chemical composition and crystalline structure.
