Hydroxyapatite, also called hydroxylapatite, alkali type calcium phosphate, calcium is apatite (Ca5 (PO4) (OH) 3) natural mineralized.

OH- base can be fluoride, chloride and carbonate ions, generate fluorine apatite or chloride matrix apatite, the calcium ions can be a variety of metal ions by ion exchange reaction, form the corresponding metal ions M apatite (M on behalf of replacing calcium metalions)

Hydroxyapatite (HAP) is the main inorganic component of human and animal bones. It can achieve chemical bond bonding with the body tissue at the interface. It has a certain solubility in the body, can release ions that are harmless to the body, can participate in metabolism in the body, stimulate or induce bone hyperplasia, and promote the defect tissue. Repair, showing biological activity. [1] 
Hydroxyapatite, also known as hydroxyapatite, a basic calcium phosphate, is a natural mineralization of calcium apatite (Ca5(PO4)3(OH)). But it is often written in the form of (Ca10(PO4)6(OH)2) to highlight that it consists of two parts: hydroxyl and apatite. The OH-based energy is replaced by fluoride, chloride and carbonate ions to form fluorine-based apatite or chloroapatite, in which calcium ions can be replaced by various metal ions by ion exchange reaction to form corresponding metal ions. M apatite (M represents a metal ion that replaces calcium ions). Hydroxyapatite (HAP) is the main inorganic component of vertebrate bones and teeth. The content of hydroxyapatite in human enamel is about 96Wt.% (92Vol.%), and about 69Wt.% in bone.Hydroxyapatite has excellent biocompatibility and biological activity, and can be used as an inducing factor for bones or teeth. It has good remineralization, desensitization and whitening effect on teeth in the field of oral health. The experiment proves that HAP particles have good biocompatibility with enamel and high affinity. The mineralized liquid can effectively form remineralization deposits, prevent the loss of calcium ions, solve the problem of enamel demineralization, and fundamentally prevent dental caries. Toothpaste containing HAP material has strong adsorption effect on salivary protein and dextran, can reduce dental plaque in patients' mouth, promote gingivitis healing, and has better prevention and treatment of rickets and periodontal disease.

Application

1. Bone replacement materials, plastic and cosmetic surgery, dental, chromatography purification, calcium supplement, is currently widely used in manufacturing with the tip of the teeth or bones composition new stuff.

2. Hydroxyapatite widely exists in the human body and milk, are mainly distributed in the human body in the bones and teeth, mainly distributed in the casein micelle in milk and whey.
