Product Overview: Hydroxyapatite (HAp), with the chemical formula Ca₁₀(PO₄)₆(OH)₂, is a calcium phosphate material typically supplied as a white powder. It is widely studied and used in ceramics, surface coatings, biomaterials, and environmental applications.

Composition and Structure:

Calcium Phosphate Material: Hydroxyapatite (HAp), with the chemical formula Ca₁₀(PO₄)₆(OH)₂, is a calcium phosphate material structurally similar to the mineral component of human bones and teeth.

White Powder Appearance: Typically supplied as a white powder, hydroxyapatite is available in different particle sizes and crystallinity levels. These characteristics influence its processing behavior and suitability for specific applications.

Low Water Solubility: Hydroxyapatite has low solubility in water and dissolves more readily under acidic conditions. Its behavior depends on factors such as pH, composition, and crystallinity.

Biomaterial Applications: Due to its similarity to natural bone mineral, hydroxyapatite is widely studied and used in bone-related materials, dental formulations, and implant coatings. Medical and dental applications require appropriate grades, testing, and regulatory compliance.

Adsorption Properties: Hydroxyapatite can interact with certain metal ions and other substances through surface adsorption and ion exchange, supporting applications in water treatment and environmental research.

Versatile Processing: Hydroxyapatite can be incorporated into ceramic materials, coatings, and composites. Selection should consider purity, particle size, calcium-to-phosphorus ratio, and the requirements of the intended application.
