CAPTAL® ’R’ unsintered hydroxylapatite is a high-purity synthetic bone mineral powder, with a Ca:P ratio of 1.67 and a high surface area of typically 6 – 20 m²/g. It is suitable for sintering into a variety of bioactive ceramic products, or for blending with polymers to form bioactive composites. Typically the HA in Captal ® ‘R’ has a crystallinity around 85 – 95%. It is sold as a non-sterile powder.
CAPTAL ® has a typical particle size distribution of:
d(10) ~ 2 μm
d(50) ~ 4 μm
d(90) ~ 6 μm
