N2 - Ceramics of hydroxyapatite (Ca10(PO4)6 (OH)2: HA) and β-tricalcium phosphate (β-Ca 3(PO4)2: β-TCP), were prepared by spark plasma sintering (SPS) at the temperatures from 800°C to 1000°C for 10 min with a heating rate of 25°C·min-1. The HA ceramics prepared at 900°C and 1000°C showed transparency. On the other hands, transparent β-TCP ceramics was obtained by SPS at 1000°C. In analysis of the densification behavior during sintering of HA and β-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.
