Development of Barium Titanate with Consistent Dielectric Properties

Abstract

There is a wide variation in the dielectric properties of barium titanate bodies, generally attributed to the changes in the BaO: TiO₂ ratio and the presence of phases other than barium titanate. By incorporating the technique of washing barium titanate calcines with hot water it was found that bodies with consistent dielectric properties can be prepared. Improvement in properties can be achieved further by repeated calcination and prolonged grinding.
