Abstract Phase formation in the systems MO-ZrO2-P2O5 (M=Mg, Ca, Sr or Ba) with various ratios of M to Zr cations and within the temperature interval from 20 to 1200°C was investigated by means of DTA, TG, XRD and IR spectroscopy. The orthophosphate phases M0.5xZr2.25−0.25x(PO4)3 with x=0−1, 3 and 7 were synthesized. Concentration and temperature limits of phase existence were found for phosphates belonging in the NaZr2(PO4)3 structural family. They exist within the regions with M to Zr ratios of 0≤x≤1 (with the exception of the Mg phases) and in the temperature interval from room temperature to 900–1700°C.
