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


Department of Nanotechnology, Materials and Energy Research Center, Karaj, Iran


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 αTCP. 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%.
