When the low temperature calcination high intensity it is low the thermal expansible porcelain and its production

摘要

PROBLEM TO BE SOLVED: To provide a high-strength, low thermal expansion ceramic which is co-fired with low resistance metals such as Ag, Au, and Cu and which achieves high mechanical strength and low thermal expansibility and to provide a method for producing the same.;SOLUTION: The high-strength, low thermal expansion ceramic containing a composite oxide having a composition denoted as equation (1) (wherein, a is 0.04-0.25 in mass ratio; and α, β, γ and δ satisfy α:β:γ:δ=7.6-13.2:4.0-10.3:13.0-30.4:53.7-72.8 in mass% ratio) and the method for producing the same are provided.;COPYRIGHT: (C)2011,JPO&INPIT
