“…With proper understanding and control, many technically important materials can be heated rapidly, uniformly, selectively, less expansively and with greater control than is possible with conventional methods [18]. With the microwave energy is possible the fast attainment of niobates, tantalates and titanates thin films such as LiNbO 3 [19], SrBi 2 Ta 2 O 9 [20], Bi 3.25 La 0.75 Ti 3 O 12 , [21], and BSTSn powders, studied in this article.…”
