Synthesis of La(Mg0.5Ti0.5)O-3 ceramics for microwave applications
La(Mg0.5Ti0.5)O-3 ceramics were prepared by a non-conventional chemical route, which was based on the Pechini method. For the synthesis of La(Mg0.5Ti0.5)O-3 powders, special attention was paid to calcination and milling conditions. Powder morphology and composition were evaluated. Fine La(Mg0.5Ti0.5)O-3 powders were obtained at lower temperatures than by conventional methods. Sintering under different conditions was also tested. Dense La(Mg0.5Ti0.5)O-3 ceramics were obtained at lower temperatures showing a single phase composition and a homogeneous microstructure. Preliminary dielectric characterization at microwave frequencies was also performed.
