Abstract
Microstructure-designed hydroxyapatite ceramics, i.e. dense ceramics and porous ceramics, were prepared by hot-pressing under hydrothermal conditions. Fully dense hydroxyapatite ceramics could be obtained from ultra-fine hydroxyapatite single crystals by sintering at 1050 °C for 3h in air, after hydrothermal hot-pressing at 300°C under 30MPa of mechanical pressing for 2h. This ceramics had homogeneous grain size of about 0. 5μm with few pores. Porous hydroxyapatite ceramics with 42% porosity, about 300μm pores in diameter, was prepared from mixture of Ca(0H)2 and (NH4) 2HP04 by sintering at 1050°C for 3h in air, after hydrothermal hot-pressing at 300 °C under 30MPa of mechanical pressing for 2h. This ceramics had comparable compressive strength of 150 ± 20MPa to that of cortical bone.
