Ceramics based on calcium phosphate powder synthesized from calcium saccharate and ammonium hydrophosphate

Abstract

A microporous ceramic with a pore size ranging from 1 to 6 μm and a relative density up to 56% was obtained from the calcium phosphate powder synthesized from aqueous solutions of monocalcium saccharate (CaC₁₂H₂₂O₁₁) and ammonium hydrophosphate. The composition of the synthesized nanosized powder is found to include hydroxyapatite and sucrose. The phase composition of the ceramic after calcination in the range from 900 to 1200°C is represented by β-tricalcium phosphate and hydroxyapatite. The resulting ceramic material can be recommended for the manufacture of bone implants.
