Ca{sub 0.5(1+} {sub x)}Zr{sub 2–x}Fe{sub x}(PO{sub 4}){sub 3} phosphates have been synthesized by a sol–gel process. The individual compounds and solid solutions obtained crystallize in the NaZr{sub 2}(PO{sub 4}){sub 3} structure (trigonal symmetry, sp. gr. R3̄). Using high-temperature X-ray diffraction, we have determined their thermal expansion parameters in the temperature range from 25 to 800°C. With increasing x, the magnitudes of their linear thermal expansion coefficients and thermal expansion anisotropy decrease. Most of the synthesized phosphates can be rated as low-thermal-expansion compounds and can be regarded as materials capable of withstanding thermal “stress.”.
