Notes:
Effects on phase evolution caused by the addition of a new sintering agent, lithium borosilicate, Li2O·B2O3·SiO2 (LBS) glass to 0.9MgTiO3–0.1CaTiO3 ceramic and resultant dielectric properties were investigated. The added LBS glass, a liquid phase sintering agent, significantly lowered the densification temperature from 1300° to about 950°C, while yielding decomposition of MgTiO3 into MgTi2O5 and Mg2TiO4. At the same time, the by-products of the decomposition reaction, MgO and TiO2, were dissolved into the glass network. Such phase evolution partly compensated the influence of deleterious glass addition so that the specimen demonstrated fairly good apparent dielectric properties.
