• — Ca 0.75 + 0.5 x Zr 1.5 Fe 0.5 (PO 4 ) 3 – x (SiO 4 ) x ( x = 0–0.5) solid solutions have been synthesized by a sol–gel process and characterized by X-ray diffraction, IR spectroscopy, and differential scanning calorimetry. As expected, the synthesized phosphatosilicates crystallize in a NaZr 2 (PO 4 ) 3 -type structure (trigonal symmetry, sp. gr. R c ). The thermal expansion of the solid solutions has been studied by high-temperature X-ray diffraction in the temperature range from 25 to 800°C. Their thermal expansion parameters have been calculated and analyzed as functions of composition. High-density ceramics based on the Ca 0.875 Zr 1.5 Fe 0.5 (PO 4 ) 2.75 (SiO 4 ) 0.25 phosphatosilicate have been produced by spark plasma sintering and their structure and properties have been studied in detail.
