Abstract

Investigations were carried out on development of a calcium carbonate ceramic with addition of potassium carbonate for regeneration of human osseous tissues. The initial materials included various calcium carbonate powders of commercial grade as well as powders obtained by chemical deposition. Porosity and strength were studied as a function of additive content and sintering temperature. The use of the additive resulted in a decrease in sintering temperature below 720°C, which allowed decomposition of calcium carbonate to be eliminated and a dense ceramic to be obtained.
