• — New NZP-type solid solutions, Na 1+2 x Zr 2– x Ni x (PO 4 ) 3 and Ca 0.5+ x Zr 2– x Ni x (PO 4 ) 3 with x = 0.10, 0.25, and 0.50, have been prepared by solid-state reactions. The synthesized samples have been characterized by X-ray diffraction and IR spectroscopy. Crystal structure of the compound CaZr 1.5 Ni 0.5 (PO 4 ) 3 has been refined by full-profile X-ray diffraction analysis method, reliability factors is R p = 4.78% and R wp = 6.45%, respectively. Thermal expansion of the phosphates has been studied by high-temperature X-ray diffraction in the temperature range 25–700°C. The synthesized compounds have been shown to be intermediate- and low-thermal-expansion materials. Using SPS method we have produced ceramic samples with a high relative density (ρ rel > 97%), based on phosphate powders. Strength characteristics (microhardness and fracture toughness) of the ceramics have been determined.
