IN268374: A process of making porous bioactive scaffolds, porous bone filler materials, nano sized calcium hydroxy apatite powder or a composite with other calcium phosphates

The process of making nano-sized calcium hydroxy apatite powder and its composite with P-Ca3 (PO4)2 (3-TCP) and other Calcium Phosphates through modified solution combustion synthesis using pure or mixed fuels has been disclosed. The phase pure nano-sized calcium hydroxy apatite and the composites comprised of a mixture of Calcium Hydroxy apatite, Beta-Tri-Calcium Phosphate and other phosphates. In accordance with this invention, the resultant product obtained by modified solution combustion synthesis is a fluffy foam-like mass composed of isometric spherical particles of 20-150 nm size. The nano-sized Calcium Hydroxy Apatite powder and its composite material can also be processed to yield porous bioactive scaffold and bone filler materials.
