Description
Hydroxyapatite Nanopowder / Nanoparticles
Purity: 99.95% | Average Particle Size: 50 nm | Appearance: White Powder
Product Overview
Hydroxyapatite (Ca₅(PO₄)₃OH·2H₂O) is the primary mineral component of human bone and tooth enamel, accounting for their rigidity and structural integrity. Its excellent biocompatibility, bioactivity, and osteoconductivity make it one of the most important materials in biomedical engineering. The hydroxide ion in hydroxyapatite can be substituted with fluoride, chloride, or carbonate to form derivative apatites, which broadens its application range in dental and orthopedic technologies.
Our high-purity hydroxyapatite nanopowder offers excellent chemical uniformity, controlled morphology, and optimal Ca/P ratio, suitable for advanced biomedical, pharmaceutical, and nanotechnology applications.
