Abstract

Tricalcium phosphate Ca3(PO4)2 (TCP), an osteoconductive as well as bioresorbable phase, has found application as bone cement and bone implant material. TCP was found to crystallize in three polymorphic modifications: β-TCP below 1180°C, α-TCP between 1180°C and 1430°C, and α-TCP above 1430°C [1]. It is mainly β-TCP and α-TCP that have gained acceptance in biomedical applications. At the moment β-TCP ceramics are used for non-load-bearing applications in oral surgery. In this investigation we were able to detect an additional but reversible phase transformation from β- to β′-TCP at 1000°C. The influence of partial Mg2+ substitution of Ca 2+ in the solid solution series of β′-TCP (Ca 1-xMgx)3(PO4)2 was determined at 1025°C ± 10°C in air. The temperatures for β′- to α-TCP phase transformation were investigated in a manner differentiated according to the different Mg2+ contents.
