Crystallized glass sealing material

Disclosed is a sealing glass composition that turns, when fired at a temperature of 900-1150° C., into a crystallized glass having a thermal expansion coefficient of 80-110×10−7/° C. in the range of 50-850° C. The composition is substantially free of both boron oxide and barium oxide, and comprises...

Zusammenfassung:	Disclosed is a sealing glass composition that turns, when fired at a temperature of 900-1150° C., into a crystallized glass having a thermal expansion coefficient of 80-110×10−7/° C. in the range of 50-850° C. The composition is substantially free of both boron oxide and barium oxide, and comprises SiO2: 43-53 mol %, CaO: 12-33 mol %, MgO: 12-33 mol %, La2O3: 1-7 mol %, and ZnO: 0-4.5 mol %.
