Dense polycrystalline β-tricalcium phosphate for prosthetic applications

Abstract

A method is described for preparing dense, polycrystalline β-tricalcium phosphate. The compressive and flexural strengths of the polycrystalline bodies sintered at a temperature of 1150° C for 1 h were found to be 459 and 138 MPa, respectively. Observation of the fracture surfaces by scanning electron microscopy indicates a predomination of transgranular failures. The polycrystalline tricalcium phosphate is non-toxic in a cell culture system. © 1982 Chapman and Hall Ltd.
