Effects of Time, Temperature and Precursor on Solid State Synthesis of α-TCP

In this study, the correlation between impurity content of reagents used (monetite and brushite both from merck), soaking time and firing temperature in the solid state synthesis of α-tricalcium phosphate (α -tcp) has been established. mg impurity promoted formation of β-polymorph as a second phase in the resultant product. the extension of firing operation also led to an increase in the amount of α- tcp, higher firing temperature with an equivalent soaking time resulted in a more purely synthesized α- tcp. the amount of α and β phases at each heating program were investigated through match software system. the highest percentage of obtained α-tcp in the resultant product with the monetite precursor containing 0.43 wt.% magnesium impurity at 1350°c and 16 hours of soaking time was about 94%.
