Zirconia ceramic, preparation method thereof and ceramic filter
The invention discloses zirconia ceramic, a preparation method thereof and a ceramic filter, and belongs to the technical field of ceramic. Crystal phases in the zirconia ceramic comprise a tetragonal crystal phase and a cubic crystal phase, the total proportion of the tetragonal crystal phase and the cubic crystal phase is 90-95%, the zirconia ceramic comprises a first stable component and a second stable component, the first stable component is magnesium oxide, and the second stable component is selected from at least one of yttrium oxide, cerium oxide, calcium oxide, aluminum oxide and lanthanum oxide. The thermal shock resistance of the zirconia ceramic can be improved, the sintering temperature is reduced, and the probability of ceramic cracks is reduced.
一种氧化锆陶瓷及其制备方法以及陶瓷过滤器，属于陶瓷技术领域。氧化锆陶瓷中的晶相包括四方晶相和立方晶相，且四方晶相和立方晶相的总占比为90～95％，氧化锆陶瓷中包括第一稳定成分和第二稳定成分，第一稳定成分为氧化镁，第二稳定成分选自氧化钇、氧化铈、氧化钙、氧化铝和氧化镧中至少一种。其能够提高氧化锆陶瓷的抗热震性能，降低烧结温度和减小陶瓷裂缝的几率。
