| Abstract: | Ceramic materials based on Ca0.5Zr2(PO4)3 and NaFeNb(PO4)3, structural analogs of NaZr2(PO4)3 (NZP), were prepared by spark plasma sintering. At sintering temperatures of 1100–1200 and 880°C and sintering times of 12 and 3 min, the relative densities reached were 99.1 and 99.9%, respectively. According to X-ray diffraction data, the sintering process caused no changes in phase composition. The ceramics had a dense, homogeneous microstructure and ranged in grain size from 0.5 to 2.5 μm. |
