Title:
APATITE COMPOSITE CERAMICS
Document Type and Number:
Japanese Patent JPS60186455
Kind Code:
A
Abstract:
This invention provides a novel apatite composite ceramic useful for implants such as artificial dental root, artificial bone or the like. The apatite composite ceramic comprises an interconnected structure of fluorapatite phase and an at least partially crystallized biologically active glass phase, which ceramic is obtained by reaction-sintering at a sintering temperature of 700 DEG -1100 DEG C. at a pressure of at least atmospheric pressure a powder mixture of a synthetic hydroxyapatite (A) and a biologically active glass (B) containing fluoride ions and having a crystallization temperature below the sintering temperature in a weight ratio of A/B ranging from 60/40 to 30/70. The reaction-sintered material has excellent biological affinity and high mechanical strength.
