江苏大学材料学院以二氧化锆(ZrO2)和三氧化钨(WO3)为原料,采用化学固相分步法制备了钨酸锆(ZrW2O8)粉体。具体工艺过程为:将球磨好的ZrO2和WO3混合物30 g(按Zr4+和W6+的量比为1∶2),在600℃、800℃和900℃下分别保温4h、8 h、12 h,之后在硅钼炉中1 200℃烧结4 h,立即取出淬火, Zirconium tungstate (ZrW2O8) powder was prepared by chemical solid phase step method from zirconia (ZrO2) and tungsten trioxide (WO3) as raw materials. The specific process is as follows: 30 g of the ball-milled ZrO2 and WO3 mixture (in a ratio of 1: 2 of Zr4 + to W6 +) is incubated at 600, 800 and 900 respectively for 4h, 8h and 12h, Sintering in silicon molybdenum furnace 1 200 ℃ 4 h, immediately remove the quenching,
