Nowadays, manufacturing of calcium phosphate biocompatible ceramics with favorable chemical and mechanical properties is still a challenge. Ceramics made of β- tricalcium phosphate are showing promises within modern bioceramic requirements. One of the possible ways of preparing β- tricalcium phosphate is through its precursor, amorphous calcium hydroxyapatite (CDHA) that can be prepared through wet precipitation method. A phase transition to β- tricalcium phosphate happens while sintering CDHA at temperature higher than 800 °C. Doping is possible by adding divalent salts while wet precipitation is occurring, which changes the properties of the final product. Analysed dopants were strontium and magnesium divalent cations whose salts had been added after wet precipitation and before sintering of the powder. X-ray diffraction pointed to shrinkage of the unit cell. Infrared spectroscopy with Fourier transformation proved purity of synthesized sample with minor addition of pyrophosphate caused by local non-stoichiometry. Thermogravimetric and differential thermal analysis determined the temperature of phase transition at ~750 °C for magnesium doped sample, while the temperature for strontium doped sample has been determined at ~775 °C. Scanning electron microscopy was used to analyse sample morphology. The differential thermal analysis has proven the possibility to use wet precipitation method to dope β-TCP and raise its phase transition temperature to α-TCP. The phase transition temperature for magnesium doped sample has been raised to the outside of the measuring parameters while for the strontium doped sample the temperature has been raised to 1300 °C.
