Abstract:

Time temperature firings as determined from the crystallization behavior of the barium titanate glass were made as a possible method of controlling crystal size. The dielectric constants and bulk densities of the devitrified composition was increased but the Curie temperature remained in the vicinity of 150 deg C and the crystal size remained unchanged. Dielectric constant versus temperature measurements of the glass were made and are discussed. Thermal expansions of the glass and crystalline phases of the devitrified bodies were determined. A careful X-ray examination reveals that the only crystalline phase present in the devitrified composition is tetragonal barium titanate, which appears more tetragonal than conventional barium titanate.
