Oxide porcelain composition, ceramic multilayer substrate, and ceramic electronic component

摘要

An oxide porcelain composition includes at least one metal element selected from Al, Si, Ba, B and Cr. The oxide porcelain composition contains about 11.5 weight percent to 60.0 weight percent of Al, in the form of Al₂O₃; about 4.0 weight percent to 70.0 weight percent of Si, in the form of SiO₂; about 4.0 weight percent to 40.0 weight percent of Ba, in the form of BaO; about 1.0 weight percent to 30.0 weight percent of B, in the form of B₂O₃; and about 0.3 weight percent to 3.0 weight percent of Cr, in the form of Cr₂O₃.
