Hydroxyapatite Micron Powder
Hydroxyapatite, also called hydroxyapatite (HA), is a naturally occurring mineral form of calcium apatite with the formula Ca5(PO4)3(OH), but it is usually written as Ca10(PO4)6(OH)2. Hydroxyapatite is a white powder that can acquire grayish, green and yellow appearance. It has a melting point of nearly 1100 °C and has a density of 3.05-3.15 g/cm3. Hydroxyapatite is chemically similar to the mineral component of bones and hard tissues in mammals. The key property of hydroxyapatite can be considered the ability to integrate in bone structures and support bone ingrowth, without breaking down or dissolving (i.e it is bioactive). It is one of few materials that are classed as bioactive, meaning that it will support bone ingrowth and osseointegration when used in orthopedic, dental and maxillofacial applications. Micron Hydroxyapatite is used in the air filters of motor vehicles to enhance the efficiency of filters in the absorption and decomposition of carbon monoxide (CO). Hydroxyapatite micron powder is also used as a provision for the electrophoresis of nucleic acids.
