Zirconia ceramic material and preparation method and application thereof
The invention provides a zirconia ceramic material and a preparation method and an application thereof. The preparation method of the zirconia ceramic material comprises the steps that second-phase SiC powder is added into ZrO2 powder, ZrO2SiC composite cast films are prepared, the ZrO2SiC composite cast films serve as interlayers and are clamped between the adjacent zirconia cast films, and toughening of a layered structure is achieved; and the second-phase SiC is dispersed and distributed in the ZrO2 ceramic, so that a dispersion toughening effect can be achieved in the whole zirconia ceramic material, and the uniformity of the toughness of the prepared zirconia ceramic material is guaranteed.
本发明提供了一种氧化锆陶瓷材料及其制备方法和用途，所述氧化锆陶瓷材料的制备方法中，在ZrO2粉体中加入第二相SiC粉体，制备ZrO2‑SiC复合流延膜片，将ZrO2‑SiC复合流延膜片用作夹层，夹设于相邻氧化锆流延膜片之间，实现层状结构增韧；使得第二相SiC弥散分布在ZrO2陶瓷中，在整个氧化锆陶瓷材料中可以起到弥散增韧的效果，以此保证制得的氧化锆陶瓷材料韧性的均匀性。
