Hydroxyapatite Nanopowder/Nanoparticles
Purity: 99.95+%, Size: 50 nm
Hydroxyapatite is a naturally occurring mineral form of calcium phosphate represented by the formula?Ca5(PO4)3OH?2H2O The OH? ion can be replaced by fluoride, chloride or carbonate, producing fluorapatite or chlorapatite. It is hydroxyapatite that gives bones and teeth their rigidity. Hydroxyapatite has a variety of applications such as orthopaedic, dental and maxillofacial applications. For applications requiring the highest uniformity in size and shape, we offer Hydroxyapatite Nanopowder/Nanoparticles with high purity and low prices.
