What is Hydroxyapatite?

Hydroxyapatite (HAp) is a naturally occurring mineral form of calcium phosphate with the chemical formula Ca10(PO4)6(OH)2. It is the main inorganic component of human bones and teeth, providing strength and rigidity. HAp is widely used in medical, cosmetic, food, and industrial applications due to its biocompatibility, osteoconductivity, and versatility.

Key Properties

• Biocompatibility: Highly compatible with human tissues.
• Osteoconductivity: Promotes bone growth and integration.
• Versatility: Can be synthesized in various particle sizes and purities for specific applications.

Different Grades of Hydroxyapatite and Their Differences

Hydroxyapatite is classified into different grades based on purity, particle size, processing, and intended application. Here's a breakdown:

1. Medical Grade Hydroxyapatite
