摘　　要：提出了用ＫＯＨ熔融分解ＢａＴｉＯ３粉体〔１〕，再用浓ＨＣｌ酸化后，用感应耦合等离子体发射光谱法（ＩＣＰ—ＡＥＳ法）测定试样中的Ｔｉ／Ｂａ比，并与化学分析法的结果作了比较，显示出ＩＣＰ—ＡＥＳ法简便，快速，结果更好。In this paper,a method for determination of Ti/Ba ratio in BaTiO 3 powder by using Inductively Coupled Plasma Atomic Emission Spectrometry (ICP—AES) has been proposed. The data of determination have teen compared with the data of chemical analysis.The comparison shows that satisfactory results can be obtained by ICP AES method. The method is simple, rapid and more accurate.
