Description
Hydroxyapatite Micron Powder, Purity: 99.5+%, Size: 3 µm
Hydroxyapatite (also known as Hydroxylapatite) is a naturally occurring mineral form of calcium phosphate, with the chemical formula Ca5(PO4)3OH·2H2O. It plays a critical structural role in the human body, being the main component that gives bones and teeth their rigidity. The hydroxide (OH−) in hydroxyapatite can be replaced by other ions such as fluoride, chloride, or carbonate, leading to the formation of compounds like fluorapatite or chlorapatite.
Our Hydroxyapatite Micron Powder, sized at 3 µm, is engineered for high purity and excellent consistency, making it ideal for demanding applications in biomedical and dental fields. This powder is suitable for use in drug and gene delivery, dental care products, and bone tissue engineering.
