钛酸钡粉体的制造方法;METHOD FOR PRODUCING BARIUM TITANATE POWEDER

摘要

根据本发明，提供一种钛酸钡粉体的制造方法，其特征系包含：于常压下将氢氧化钡水溶液保持在80℃至沸点为止的温度，并将BET比表面积在200至400m 2 /g的范围且藉由X射线绕射所测得之(101)面之绕射峰值的半值宽在2.3°至5.0°的范围之锐钛矿(Anatase)型含水氧化钛的水浆液加入于上述氢氧化钡水溶液，使上述氢氧化钡与上述含水氧化钛反应而得到钛酸钡前驱物的水浆液之步骤；以及接着对如此得到之钛酸钡前驱物进行24小时以上的水热处理，而得到钛酸钡粒子之步骤。 According to the present invention, provided is a method for producing powder comprising: a step of maintaining an aqueous barium hydroxide solution at a temperature of 80℃ to boiling temperature under an atmosphere, and adding thereto an anatase-type hydrous titanium oxide having a BET specific surface area in a range of 200 to 400 m 2 /g and a half bandwidth at 2.3° to 5.0°
