摘要
着重阐述了用化学共沉淀法制备Ｂａ２Ｔｉ９Ｏ２０超微粉的研究，讨论了ｐＨ值、分散剂及焙烧温度对粉料性能的影响。实验发现，用化学共沉淀法即可制备出纯度高且粉体粒度为０．
The preparation of Ba 2Ti 9O 20 ultrafine powder with chemical coprecipitation was studied here.The effects of the pH value,dispersant and presintering temperature on properties of powders were discussed as well.The results of experiment indicated that the ultrafine powder with high purity could be produced by using chemical coprecipitation.The average particle size of the prepared powder was about 0.42 μm.
