pretreatment of tungsten added BaTiOx ceramics was performed to improve the recovery of Ba, Ti and W. BaTiOx ceramics were digested with HF : HCl ( 1 : 2 ) mixture in an acid digestion bomb at 220℃ for 3 hrs. The concentration of Ba, Ti and W were determined by ICP-AES. Recoveries of Ba, Ti and W were 99.6% , 99.8% and 99.2%, respectively. And their C.V. values were 1.02%, 0.73% and 1.79%. Using this method, the analytical results of Ba, Ti and W for a real sample were obainted to be 25.9% (w/w), 38.8% (w/w) and 3.31% (w/w), respectively.
