A glass used to liquid‐phase sinter BaTiO 3 was developed and its properties were tested to determine the feasibility of using this glass to aid densification behavior. Glass was added to pure BaTiO 3 powder and pressed into dimpled pellets with glass contents varying from 4 to 20 vol%. The breakdown strength was measured and compared with pure BaTiO 3 and two commercially available dielectric materials. Liquid‐phase sintering increased the breakdown strength of pure BaTiO 3 for all the compositions tested. The breakdown strength of the samples containing 20 vol% glass additions was increased by a factor of 2.8 compared with pure BaTiO 3 .
