The preparation of biphasic mixtures (HAP + 
-TCP) of controlled ratios with the combined substitutionof essential biocompatible trace elements (Na, Mg, and F) was carried out by an aqueous precipitationmethod. The results showed that incorporated elements have played a significant role in the thermalstability of the apatites up to 1400 
C, and that increased calcium deficiency in the apatites has led to theformation of a higher proportion of -TCP in the biphasic mixtures. However, minor discrepancies inthe structural parameters due to the incorporated trace elements and the matching of phases of thesynthesized powders with respect to the stoichiometric HAP were apparent from the present investigation.
