Prepd from Ca(NO3)2 and KH2PO4; from calcium phosphate, dibasic; from Ca(NO3)2.4H2O and (NH4)3PO4 plus NH4OH.

Dense hydroxyapatite ceramics are made by compressing calcium phosphate solids from a very fine powder form, known as greenstate, into a pellet which is then subjected to a heat treatment that causes the powder particles to fuse together by means of solid-state diffusion.
