Buying Guide of Medical Grade HA Microspheres

1. Molecular Structure of Hydroxyapatite Microspheres

Hydroxyapatite Microspheres Molecular Structure

2. What are applications of medical HAP microspheres?

  • 3D bioprinting material
  • Medical implant materials such as hydroxyapatite bioceramics as well as thermal spray coating for medical implants.
  • Artificial bone repair scaffold material
  • Dermal fillers

3. What are the synthesis methods for HAP microspheres?

The raw material of our calcium phosphate is produced by solid-phase method or liquid-phase method according to different uses.

The large HAP particles are made spherical through granulation process (the granulation process is a technology to make out spherical morphology), and then the sintering process is performed.

At last, sieving the HA microspheres in order to achieve the ideal particle size range. Besides, we use spray drying method to get spherical HA microspheres with small particle size.

4. What are advantages of spherical HA/HAP?

Hydroxyapatite (Ca10 (PO4) 6 (OH)2), abbreviated as HA or HAP, has similar chemical composition and structure to the bone tissue of living organisms. It has good biocompatibility and biological activity.

HA microspheres with spherical morphology have high packing density and uniform stress distribution, which can increase the powder fluidity and can reduce the intensity, which makes the biocoating more smooth.

5. Why choose HA microspheres from EPRUI?
