High-density quartz-zirconium oxide composite ceramic and preparation method thereof
The invention discloses high-density quartz-zirconium oxide compositeceramic and a preparation method thereof. The composite ceramic is mainly composed of a quartz phase, a zirconium oxide phase, a zirconite phase and a glass phase. In the high-density quartz-zirconium oxide composite ceramic, the content of the quartz phase is 4.7 to 67.1 wt%, the content of the zirconium oxide phase is 6.5 to 60.5 wt%, the content of the zirconite phase is 5.0 to 63.2 wt%, and the content of the glass phase is 15.1 to 28.3 wt%. The preparation method comprises the following steps: mixing aeolian sand and zirconium oxide, and carrying out ball milling to obtain a mixed raw material; drying and crushing the mixed raw materials; carrying out compression molding on the crushed mixed raw materials to obtain a composite ceramic green body; and sintering the composite ceramic green body to obtain the high-density quartz-zirconium oxide composite ceramic. According to the invention, the content of quartz, zirconium oxide, zirconite and glass phase in the ceramic is adjusted by adjusting the addition amount of zirconium oxide, the sintering temperature and the heat preservation time, so that the composite ceramic with different mechanical properties is obtained, and the series of ceramics meet the application requirements of various occasions (cost and performance).
