Abstract

The dissolution kinetics of type B carbonate apatite (CAp) disks sintered at different temperatures were investigated under acidic conditions similar to an osteoclastic desorption process in bone remodeling. The type B CAp disks, which were uniaxially pressed at 98MPa and sintered at temperatures of 600 to 700°C, showed single crystalline phase and a high relative density of 60-62% compared to the stoichiometric density of 3.16g/cm ³ of hydroxy apatite (HAp). The dissolution rate of type B CAp disks sintered at 650°C was 3.5 times faster than that of HAp disks at 650°C. These results indicate that the Type B CAp sintered disks show potential use as a biodegradable material for artificial bone.
