| Abstract: | An XRF spectrometric method has been developed for the determination of elements in barium titanate china clay with a fusion technique,in which a new mixed flux of the Li 2B 4O 7 and LiBO 2 was used.A series of barium titanate standard samples were prepared. Interelement absorption and enhancement effects were corrected by using the empirical coefficient method and Sr,Ca as internal standard elements. The precision and accuracy of the method were satisfactory for the demands of production. |
