Multilayer glass ceramic substrate and process for producing the same. |
摘要 |
A multilayer glass ceramic substrate having a plurality of conductor layers each laminated through a glass ceramic layer. The glass ceramic layer has a composition comprising of alumina, borosilicate magnesium glass and cordierite crystal produced by chemical reaction between alumina and borosilicate magnesium glass. The content of alumina is 12 to 59.6 wt%, the content of borosilicate magnesium glass is 18 to 69.6 wt%, the content of the cordierite crystal is 1 to 50 wt% and the sum of components is 100 wt%. The multilayer glass ceramic substrate shows improved mechanical strength. |
