摘要ＰＲＥＰＡＲＡＴＩＯＮＯＦＨＩＧＨＰＵＲＩＴＹＡＮＤＮＡＮＯＭＥＴＥＲＳＣＡＬＥＢＡＲＩＵＭＴＩＴＡＮＡＴＥＰＯＷＤＥＲＳ①ＷａｎｇＫａｉｙｉ，ＬｉａｏＢｏ，ＬｉｕＹｅｘｉａｎｇ，ＷｅｉＱｉｎｇ，ＱｉａｎＤｏｎｇ，ＣｈｅｎＸｉａｏｙｉａｎｄＬａｉ... By using H_2TiO_3 and Ba(NO_3)_2 as the raw materials, and (NH4)2CO_3 as the precipitant, high purity(>99.7%) and superfine(<1 μm) BaTiO_3 powders were obtained by coprecipitation method. Then the nanometerscale BaTiO_3 powders were prepared with the mechanophysical solid effect equipment. The equipment of the present process is characterized by simplicity, convenience and low capital cost. Hence it is suitable for industrial production.
