摘要
采用正交试验方法研究了溶胶共沉淀法制备ＺｒＯ２－Ｙ２Ｏ３陶瓷粉末的工艺过程。对粉体进行了粒度、ＸＲＤ、ＳＥＭ观察，结果表明：对粉体粒度影响最大的是母液浓度，而母液温度则无明显影响；母液ｐＨ值不同时影响ＺｒＯ２的晶体结构。正交试验优化出了用ＮＨ４ＨＣＯ３作为沉淀剂制备ＺｒＯ２粉末的最佳工艺参数，即：母液浓度１．０ｍｏｌ／Ｌ，ｐＨ＝５～６。事实表明，用此法制粉成本低，周期短，效率高。
The 9 mol% Y 2O 3 ZrO 2 powders were fabricated with sol wet chemical method by the orthogonal experiment.Results from grain size analysis,XRD,and SEM show that concentration of solution has a great effect on the grain size,and pH value of solution can affect the ZrO 2 crystal structure.When NH 4HCO 3 is used as precipitant,the optimal technique parameters are concentration of 1 0 mol/L and pH of 5～6.Facts show that this method can low cost,shorten cycle,and improve efficiency.
