LOW TEMPERATURE SINTERED CERAMIC COMPOSITION, CERAMIC SINTERED COMPACT, MULTILAYER TYPE CERAMIC ELECTRONIC PARTS, AND PRODUCTION METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a low temperature sintered ceramic composition for obtaining a ceramic sintered compact which has high deflective strength and a high quality coefficient.;SOLUTION: For example, as a low temperature sintered ceramic composition for obtaining a ceramic sintered compact composing a ceramic layer 2 provided in a multilayer ceramic substrate 1, the one containing a calcined material obtained by subjecting a mixture of each powder of a heat treated material of kaolinite clay and a Ca compound such as CaCO₃ and Ca(OH)₂ to heat treatment and MgAl₂O₄ (spinel) powder is used. The spinel powder of 30 to 80 pts.wt. is added to 100 pts.wt. of the calcined material.;COPYRIGHT: (C)2003,JPO
