• New phosphates with NaZr2(PO4)3 structure of the B0.5FeTa(PO4)3-type (where B-Ca, Sr, Ba) are synthesized and characterized by X-ray diffraction analysis and IR-spectroscopy. The heating behavior of the phosphates is studied using high-temperature X-ray crystallography in the range 15-625 deg C. The unit-cell parameters, the coefficients of thermal expansion alphaa, alphac and their thermal expansion anisotropy |alphac - alphaa| of the phosphates under study are determined and the dependences of these characteristics on the nature of cations are established and analyzed.
