Abstract
Disclosed is a high-strength, high-expansion crystallized glass composition that, by being fired at not less than 850° C., can be used at high temperatures at not less than 950° C. The composition is a sealing glass composition substantially free of boron oxide and comprising the following components, in mol %, SiO: 40-50%, ZnO: 16-30%, BaO: 5-25%, CaO: 0-25%, AlO: 0-5%, and RO: not less than 44% (wherein R denotes one or more species of Mg, Ca, Sr, Ba, and Zn).
