Zirconium oxide toughened aluminum oxide composite material, preparation method thereof and zirconium oxide toughened aluminum oxide ceramic
The invention relates to the field of preparation and development of nano composite materials, in particular to a zirconium oxide toughened aluminum oxide composite material, a preparation method thereof and zirconium oxide toughened aluminum oxide ceramic. The method provided by the invention comprises the following steps: dispersing raw materials comprising a zirconium source and aluminum oxide to obtain a zirconium oxide toughened aluminum oxide composite material; according to the invention, dispersion is carried out at a linear speed of 24-35 m/s; the dispersion time is 1 to 10 minutes. According to the invention, the high rotating speed of mechanical fusion equipment is creatively utilized, so that the powder is subjected to high-linear-speed shearing friction to generate high temperature, zirconium oxide and aluminum oxide are fully and uniformly mixed and strongly combined in a relatively short time, the high-quality and stable ZTA powder is prepared, and the production efficiency is improved to 300kg/min. Experiments show that the ZTA ceramic prepared from the ZTA powder has the density of 4.15 g/cm < 3 >, the three-point bending strength of 815 MPa and the normal-temperature heat conductivity of 31 W/m.K.
本发明涉及纳米复合材料制备开发领域，具体是一种氧化锆增韧氧化铝复合材料及其制备方法和氧化锆增韧氧化铝陶瓷。本发明提供的方法包括：将包括锆源和氧化铝的原料进行分散，得到氧化锆增韧氧化铝复合材料；本发明以24～35m/s的线速度进行分散；所述分散的时间为1～10min。本发明创新性地利用机械融合设备的高转速，使粉体高线速度剪切摩擦产生高温，实现了氧化锆与氧化铝在较短时间内充分均匀混合和强力结合，制备得到高质量稳定的ZTA粉体，生产效率提高到300kg/min。实验表明，本发明制得的ZTA粉体制成ZTA陶瓷，密度为4.15g/cm3，三点弯强度为815MPa，常温热导率为31W/m·K。
