Effects of La_2O_3 Additions on Microstructure and Microwave Dielectric Properties of Mg_2TiO_4 Ceramics
Source abstract
Abstract
(1-x)Mg2TiO4-xLa2O3 ceramics were prepared corresponding to 0x0.1 by the conventional solid-state reaction methed. Their microstructures, dielectric properties were investigated. For the sample without La2O3, its average grain size was more than 60μm. With La2O3 added, the grain sizes became smaller and new crystal phase La0.66TiO2.99 appeared. In the meantime, dielectric constants of materials increased and the quality factor Q values can be up to 16558(10GHz) at x=0.03. Besides, microstructures of materials also changed obviously.
