Zirconium-based composite ceramic material, preparation method thereof and ceramic structural member
The invention discloses a zirconium-based composite ceramic material, a preparation method thereof and a ceramic structural member. The zirconium-based composite ceramic material comprises a zirconium oxide matrix; the LaAl11O18 phase and the Zn2SiO4 phase are dispersed in the zirconium oxide base body. The LaAl11O18 phase dispersed in the zirconium oxide matrix has the effects of reducing the light transmittance, the density and the dielectric constant of the zirconium-based composite ceramic material and improving the toughness and the impact resistance of the zirconium-based composite ceramic material; meanwhile, the Zn2SiO4 phase dispersed in the zirconium oxide matrix has the effects of reducing the sintering temperature in the preparation process of the zirconium-based composite ceramic material and improving the strength and impact resistance of the zirconium-based composite ceramic material. Therefore, the zirconium-based composite ceramic material disclosed by the invention has relatively high hardness, toughness and impact resistance, and relatively low density, dielectric constant and light transmittance.
本发明公开了锆基复合陶瓷材料及其制备方法和陶瓷结构件,锆基复合陶瓷材料包括:氧化锆基体;以及分散在所述氧化锆基体中的LaAl11O18相和Zn2SiO4相。在氧化锆基体中分散的LaAl11O18相具有降低锆基复合陶瓷材料的透光率、密度和介电常数、以及提高锆基复合陶瓷材料的韧性和抗冲击性的作用;同时,在氧化锆基体中分散的Zn2SiO4相具有降低锆基复合陶瓷材料的制备过程中的烧结温度以及提高锆基复合陶瓷材料的强度和抗冲击性的作用。由此,本发明的锆基复合陶瓷材料同时兼具较高的硬度、韧性和抗冲击性、以及较低的密度、介电常数和透光率。
