Hydroxyapatite, also known as hydroxyl apatite is calcium apatite (Ca5 (PO4) (OH) 3) natural mineralized.But is often written as (Ca10 (PO4) 6 (OH) 2) to highlight the form of it is made up of two parts: the hydroxyl apatite.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 metal ions). Chinese name: hydroxyapatite English name: Hydroxyapatite;hydroxylapatite Products, HAP Minor: Ca10 (PO4) 6 (OH) 2 Son: 1004 Physical and chemical properties: melting point: 1650 , weight: 3.16 g/cm, solubility: 0.4 parts per million, the Ca/P: 1.67 Crystal structure: hexagonal system Product specifications: 99% Product efficacy: hydroxyapatite is mainly inorganic components of human bone tiue.After implanted, calcium and phosphorus can free surface is absorbed by the body, and grow a new organization.Studies have proved that hydroxylapatite grain more fine, the higher the biological activity.Tooth enamel on the surface of the main ingredients of hydroxyapatite.Hydroxyapatite can be obtained by make your own way.Methods of hydroxyapatite powder making a lot of, more common methods include precipitation, hydrolysis method, hydrothermal method and solid phase method, etc.The equipment of hydrothermal method is complicated and expensive.Precipitation law is compared with hydrothermal method, the operation is simple, cheap equipment, large capacity, at present most of this kind of method is given priority to.But the precipitation has some disadvantages, such as powder easy together, the quality is not stable, and so on. Product use: white and healthy Remove plaque To improve the gum problems Prevent tooth decay Pure and fresh breath Product application: bone substitute materials, plastic and cosmetic surgery, dental, chromatography purification, calcium supplement, is currently widely used in manufacturing the tip of the teeth or bones composition new stuff. Packing: 1 kg/bag Storage conditions: sealed, avoid light, moistureproof
