✦ Synopsis

Synthesis of Calcium Hydroxyapatite-Tricalcium Phosphate (HA-TCP) Composite Bioceramic Powders and Their Sintering Behavior.

-The HA-TCP composite powders are synthesized, for the first time, from aqueous solutions by a novel, one-step chemical precipitation technique. The starting materials consist of Ca(NO 3 ) 2 •4H 2 O and (NH 4 ) 2 HPO 4 . The composite bioceramic powders are prepared with compositions of 20-90 wt.% HA (the balance is the TCP phase). The pellets prepared from the composite powders are sintered to almost full density in a dry air atmosphere at ≈ 1200 • C. -(KIVRAK, N.;
