Synthesis and evaluation of porous hydroxyapatite prepared by hydrothermal treatment and subsequent sintering method

Abstract

Hydrothermal treatment and subsequent post sintering were used to fabricate porous and strong hydroxyapatite. Here, steam curing method was used as a hydrothermal treatment and subsequent post sintering treatment was done in air. As a result, samples prepared by steam curing and subsequent post sintering had higher porosity and compressive strength than those prepared by normal sintering process because of the structural changes introduced during steam curing and subsequent post sintering. Moreover, the effect of synthetic condition of these processes on the microstructure for porous hydroxyapatite was investigated.
