Lanthanum hexaboride and zirconium diboride composite ceramic and preparation method thereof
The invention discloses lanthanum hexaboride and zirconium diboride composite ceramic and a preparation method thereof. In the composition of the lanthanum hexaboride and zirconium diboride composite ceramic, the molar ratio of lanthanum hexaboride to zirconium diboride is (60-90): (40-10), and the average grain size of the lanthanum hexaboride and zirconium diboride composite ceramic is 20-1200 nm. According to the preparation method, the technological process is simple, raw materials are low in price, industrial production equipment is adopted, so that industrial production is facilitated, and the synthesized lanthanum hexaboride and zirconium diboride composite ultra-fine grain ceramic is small in grain and high in hardness. The material prepared by the method also has excellent mechanical properties, shows attractive application potential in an extreme environment, and has the possibility of being applied to large-scale industrial production.
本申请公开了一种六硼化镧二硼化锆复合陶瓷及其制备方法。该六硼化镧二硼化锆复合陶瓷的组成中六硼化镧与二硼化锆的摩尔比在(60‑90):(40‑10)之间，其平均晶粒尺寸为20‑1200nm。本发明的制备方法不仅工艺过程简单、原料价格低廉、设备为工业化生产设备从而便于工业化生产，而且合成的六硼化镧二硼化锆复合超细晶陶瓷晶粒细小、硬度高。该方法制备的材料还具有优异的力学性能，在极端环境下展示出诱人的应用潜力，并且具有应用于大规模工业生产的可能。
