Professional Hydroxyapatite Powder Manufacturer, Providing You With Excellent Products
Description:
Hydroxyapatite powder (Ca10(PO4)6(OH)2) serves as the primary ingredient in synthetic bone ash, and in many respects, the two can be considered identical substances. This powder is a naturally occurring mineral variant of calcium apatite and plays a crucial role in the structure of bones and teeth, offering both support and strength.
Comprising calcium, phosphate, and hydroxyl ions, hydroxyapatite closely mimics the mineral makeup of human bone. Its remarkable biocompatibility makes it an ideal candidate for various biomedical applications, especially in the fields of bone regeneration and repair.
