Synthesis of La(Mg0.5Ti0.5)O3 ceramics for microwave applications

La(Mg_0.5Ti_0.5)O₃ ceramics were prepared by a non-conventional chemical route, which was based on the Pechini method. For the synthesis of La(Mg_0.5Ti_0.5)O₃ powders, special attention was paid to calcination and milling conditions. Powder morphology and composition were evaluated. Fine La(Mg_0.5Ti_0.5)O₃ powders were obtained at lower temperatures than by conventional methods. Sintering under different conditions was also tested. Dense La(Mg_0.5Ti_0.5)O₃ ceramics were obtained at lower temperatures showing a single phase composition and a homogeneous microstructure. Preliminary dielectric characterization at microwave frequencies was also performed.
