Synthesizing Process and sinterability of Ba(Mg1/3Ta2/3)O3
Ba(Mg1/3Ta2/3)O3合成过程及烧结性的研究

Ba(Mg1/3Ya2/3)O3 solid-state formation reactions and its sinterability were studied in relation with different raw materials, Ta2O5.xH2O and T2O5 raw materials with different phasestructure and grain size were employed as the source Ta2O5, along with BCO3 and MgO. Theexperiment results indicated that the adoption of Ta2O5. xH2O can retard the intermediate phaseand leads to more complete reaction at lower temperature than that with Ta2O5, which is due tothe local stoichiometric homogeneities of the mixed powder and the phase transformation Ta2O5from Ta2O5. xH2O. The sinterability of the powder prepared from Ta2O5. xH2O is much betterthan that of the powder from Ta2O5.
