<jats:p> <jats:bold> Effects on phase evolution caused by the addition of a new sintering agent, lithium borosilicate, Li <jats:sub>2</jats:sub> O·B <jats:sub>2</jats:sub> O <jats:sub>3</jats:sub> ·SiO <jats:sub>2</jats:sub> (LBS) glass to 0.9MgTiO <jats:sub>3</jats:sub> –0.1CaTiO <jats:sub>3</jats:sub> 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 MgTiO <jats:sub>3</jats:sub> into MgTi <jats:sub>2</jats:sub> O <jats:sub>5</jats:sub> and Mg <jats:sub>2</jats:sub> TiO <jats:sub>4</jats:sub> . At the same time, the by‐products of the decomposition reaction, MgO and TiO <jats:sub>2</jats:sub> , 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. </jats:bold> </jats:p>
