Hydroxyapatite (CAS 1306-06-5) Suppliers and Product Information

Hydroxyapatite is a naturally occurring mineral form of calcium apatite. It is the main component of bone and teeth, making up about 50% of bone mass. Due to its biocompatibility and bioactivity, hydroxyapatite is widely used in medical and dental applications, including bone grafts, implant coatings, and as a filler material in cements and polymers.

Frequently Asked Questions about Hydroxyapatite

Q: What are the main applications of hydroxyapatite?

A: Hydroxyapatite is primarily used in biomedical applications such as artificial bone and teeth, prosthetic aids, bone fillers, and coatings for metal implants. It is also used in chromatography for protein and enzyme separation, as well as in various industrial applications like catalysts and gas sensors.

Q: How is hydroxyapatite prepared?

A: Hydroxyapatite can be prepared through various methods, including precipitation from aqueous solutions, solid-state reactions, and hydrothermal synthesis. Commercial production often involves using phosphate rock as a starting material.

Q: What are the key properties of hydroxyapatite?

A: Hydroxyapatite is biocompatible, non-toxic, and has excellent osteoconductive properties. It has a unique crystal structure that allows for ion substitution, which can modify its properties. It is also thermally stable and has a high affinity for proteins and other biomolecules.

Q: Is hydroxyapatite safe for use in medical applications?

A: Yes, hydroxyapatite is generally considered safe for medical use due to its biocompatibility and similarity to natural bone mineral. However, as with any medical material, its use should be under professional medical supervision.
