MANUFACTURE OF LEAD GROUP DIELECTRIC PORCELAIN COMPOSITION

摘要

PURPOSE:To provide the method of manufacturing a lead group dielectric porcelain composition which can always have desired electric characteristics. CONSTITUTION:A material containing not less than 75 mole percent of PbO (litharge phase) is used for lead oxide in the method of manufacturing a lead group dielectric porcelain composition formed by calcining a raw-material compound containing the lead oxide more excessively than the lead oxide content of a target composition; molding a product obtained through this calcining process; and baking a product obtained through this molding process.
