Phase Transition of Synthesizing Tetracalcium Phosphate in a Solid-state Reaction

Abstract

Abstract: The phase transition course of synthesizing tetracalcium phosphate in a solid-state reaction was investigated
by TGA-DSC, XRD and FTIR. The results show that the phase transformations occurring over 1200℃ are consistence with the high temperature phase
diagram of CaO-P₂O₅-H₂O. In view of lack of the low temperature phase diagram, the phase transitions below 1200℃ can offer significant
data to draw it; understanding the whole course of phase evolution contributes to optimum the synthesizing process to get pure TTCP, the most important
biomaterial in the field of calcium phosphate cement.

Key words: tetracalcium phosphate, solid-state phase reaction, phase transitions, bioceramic
