Hydroxyapatite Powder, also known as Calcium Hydroxyapatite or Nano Hydroxyapatite, is a naturally occurring calcium phosphate mineral with the chemical formula Ca₁₀(PO₄)₆(OH)₂. It is the primary inorganic component of human bones and teeth, making it a highly bioactive material for use in orthopedics, dentistry, personal care, and biomedical engineering.
We supply high-purity hydroxyapatite in both microcrystalline and nanoparticle forms, with mesh sizes ranging from 2μm to 60nm, designed to meet diverse technical and regulatory requirements.
