Zirconia ceramic as well as preparation method and application thereof
The invention relates to zirconia ceramic as well as a preparation method and application thereof. The zirconia ceramic comprises a zirconia matrix, a stabilizer and a flexibilizer, wherein the stabilizer is one or more of yttrium oxide, erbium oxide, neodymium oxide and samarium oxide, and the flexibilizer is niobium oxide and/or tantalum oxide; based on the total molar weight of the zirconia ceramic, the content of the stabilizer is 2-4 mol%, the content of the flexibilizer is 0.45-1.4 mol%, and the molar percentage content difference between the stabilizer and the flexibilizer is 1.5-2.6 mol%. By controlling the contents of the stabilizer and the flexibilizer, the stabilizer and the flexibilizer are matched with each other, so that the zirconia ceramic is good in toughness, good in impact resistance and good in thermal aging resistance.
本发明涉及一种氧化锆陶瓷及其制备方法和应用，该氧化锆陶瓷包含氧化锆基体、稳定剂和增韧剂，所述稳定剂为氧化钇、氧化铒、氧化钕和氧化钐中的一种或多种，所述增韧剂为氧化铌和/或氧化钽；以氧化锆陶瓷的总摩尔量为基准，所述稳定剂的含量为2‑4mol%，所述增韧剂的含量为0.45‑1.4mol%，所述稳定剂与所述增韧剂的摩尔百分含量差值为1.5‑2.6mol%。通过控制稳定剂与增韧剂的含量，两者相互配合，使氧化锆陶瓷韧性好、抗冲击性能好，且具有良好的耐热老化性能。
