The effects of strontian (SrO) content on the phase composition, microstructure, thermal shock resistance, and sintering properties of CaZrO3 were evaluated. CaZrO3 with different SrO contents (0, 1, 2, 4 wt.%) was synthesized by solid-state reaction. Zirconium oxide (ZrO2) and calcium carbonate (CaCO3) were used as raw materials, and SrO was added in varying contents. The SrO content played a key role in densification and grain refinement during the sintering process. Ceramic with relative density up to 90.82% and greatest flexural strength (252.82 MPa) was obtained by adding 4 wt.% strontia. Additionally, the SrO content affected the microstructures of the samples after sintering and quenching with liquid nitrogen. Furthermore, a significant effect on the densification process and the crack propagation mode transition was also observed.
