摘要
为获取可用于陶瓷膜支撑体烧结的、粒径分布合理的原料粉体,实验中以粒径500 M的氧化铝粉体为原料,探索其湿法球磨最优条件。在不同球磨时间和球料比条件下进行球磨,对比球磨效果,测定球磨后粉体的粒径及分布并综合考虑成本因素后得出结论。实验结果表明,球料比(9~11)∶1、球磨时间9~10 h为最优球磨条件。后续实验则表明,在最优球磨参数下所得粉体粒径较均一,可直接用于烧结耐高温、高强度的陶瓷膜支撑体。
The paper is mainly about optimizing wet ball milling conditions using alumina powder as raw materials,comparing milling results on the different conditions including milling time and the ball-to-powder ratio,and other associated factors have been considered to optimize the condition including economic factors.Experimental results show that the best condition is that the ball-to-powders ratio is(9-11)∶1 and the best milling time is 9-10 h.The following experimental results show that the powder milled on the best wet ball mill conditions can be sintered directly into ceramic support with high temperature resistance and high mechanical strength.
