Effect of Liquid-phase Sintering on the Breakdown Strength of Barium Titanate
A glass used to liquid-phase sinter BaTiO3 was developed and its properties were tested to determine the feasibility of using this glass to aid densification behavior. Glass was added to pure BaTiO3 powder and pressed into dimpled pellets with glass contents varying from 4 to 20 vol%. the breakdown strength was measured and compared with pure BaTiO3 and two commercially available dielectric materials. Liquid-phase sintering increased the breakdown strength of pure BaTiO3 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 BaTiO3.
