摘要：
Ceramics of hydroxyapatite (Ca-10(PO4)(6)(OH)(2): HA) and beta-tricalcium phosphate (beta-Ca-3(PO4)(2): beta-TCP), were prepared by spark plasma sintering (SPS) at the temperatures from 800 degrees C to 1000 degrees C for 10 min with a heating rate of 25 degrees C(.)min(-1). The HA ceramics prepared at 900 degrees C and 1000 degrees C showed transparency. On the other hands, transparent beta-TCP ceramics was obtained by SPS at 1000 degrees C. In analysis of the densification behavior during sintering of HA and beta-TCP by SPS, dominant sintering mechanism was plastic flow in the early stage of densification. Transparent ceramics should be the most suitable materilas to investigate the interface between human cells and ceramics.
