Structure analysis on the Ba3Mg(Ta1−xNbx)2O9 ceramics: Coexistence of order and disorder

Characterization of BaMg1/3(Ta1−xNbx)2/3O3 ceramics obtained by a modified Pechini method

“…There cannot be made correlations between Q × f and other parameters. On the other hand, it is suggested that the substitution of the tantalum atoms with niobium atoms improves the sintering process, consequently the quality factor if the substitution percentage is under 25% [8,10]. In our case, the highest value was obtained for the BaMg 1/3 Ta 2/3 O 3 sample sintered at 1600 • C for 4 h, 74,393 GHz.…”
