Captal ® Amorphous Calcium Phosphate ‘1.5’ is a high-purity, non-crystalline, medical grade product, with a nominal Ca:P ratio of 1.5. Due to the nano-sized crystallites contained within, it is amorphous to X-Rays. The surface area of CAPTAL ® ACP is high (50 – 90 m²/gram), reflecting its porous nature. It is used in applications where further heat processing crystallises the lattice once the powder is formed into the required product. When heated above 900 °C under the correct sintering regime, it will form fully crystalline β-TCP.
CAPTAL® ‘ACP 1.5’ is available with a spherical morphology, with average particle size, d(50), of 15 – 30 μm, or with an angular morphology as granules with a d(50) from 60 μm up to 500 μm. It is sold as a non-sterile powder.
