Abstract

A method for producing ceramic dielectrics containing a water soluble metal acid or salt includes making a mixture by kneading a water soluble metal acid or salt, particulates, sintering auxiliaries and water, mixing the mixture with a binder and plasticizer to form a slurry, and forming a sheet from the slurry by drying and sintering.
