摘要
用共沉淀－超临界流体干燥法合成ＣａＯ－ＺｒＯ２（１５ｍｏｌ．％ＣａＯ）复合氧化物超微粉末，并对粉末的烧结性能进行了研究。实验表明，该法合成的粉末具有很高的烧结活性，能在较低的温度及较短的时间内完成致密化过程。４００℃，２ｈ煅烧的粉体加压成型后于１１００℃下保温０．５ｈ，其体积密度可达理论值的９８．２％，开口气孔仅为０．０００８ｃｍ３／ｇ。
CaO-ZrO 2 (15mol.%CaO) ultrafine powder was prepared by coprecipitation-supercritical fluid drying method, and its sintering behaviour was studied. The experiments show that powder obtained by this method has high sinterability. Powder calcined at 400℃ could be sintered to attain 98 2% of theoretical density at 1100℃ for 0.5h, and specific pore volumne was 0.0008cm 3/g.
