Zirconium oxide composite ceramic and preparation method thereof, shell assembly and electronic equipment
The invention provides zirconium oxide composite ceramic. The zirconium oxide composite ceramic comprises the following phases in percentage by weight: 42.9 to 84.6 percent of doped stable tetragonal phase zirconium oxide, 7.8 to 31.7 percent of zirconium silicate, 5.9 to 17.8 percent of zinc aluminate and 0.1 to 4 percent of cobalt ferrite, wherein the doped stable tetragonal phase zirconium oxide is a solid solution formed by niobium pentoxide and/or tantalum pentoxide, yttrium oxide and zirconium oxide; and based on the element content of the zirconium oxide composite ceramic, the weight percentage of yttrium is 1.7-5.5%, and the weight percentage of niobium and/or tantalum is 0.7-2.8%. The zirconium oxide composite ceramic can effectively solve the technical problems of low toughness, poor impact resistance, high processing difficulty and high light transmittance of existing zirconium oxide ceramic, and the zirconium oxide composite ceramic is light green and has strong appearance expressive force. The invention further provides a preparation method of the zirconium oxide composite ceramic, a shell assembly and electronic equipment.
本申请提供了一种氧化锆复合陶瓷，所述氧化锆复合陶瓷包括以下重量百分比的物相：42.9‑84.6％掺杂稳定四方相氧化锆、7.8‑31.7％硅酸锆、5.9‑17.8铝酸锌和0.1‑4％钴铁氧体；所述掺杂稳定四方相氧化锆为五氧化二铌和/或五氧化二钽、氧化钇和氧化锆形成的固溶体，其中，以所述氧化锆复合陶瓷元素含量为基准，钇的重量百分比为1.7‑5.5％，铌和/或钽的重量百分比为0.7‑2.8％。该氧化锆复合陶瓷能够有效解决现有氧化锆陶瓷的韧性低，抗冲击性差，加工难度高，以及透光率高的技术问题，且该氧化锆复合陶瓷为浅绿色，外观表现力强。本申请还提供了氧化锆复合陶瓷制备方法、壳体组件和电子设备。
