Title:
GLASS COMPOSITION FOR SEALING
Document Type and Number:
WIPO Patent Application WO/2016/129543
Kind Code:
A1
Abstract:
This glass composition provides a crystallized glass having a high coefficient of thermal expansion of at least 130 x 10－７/˚C when powdered and burned at a temperature of 850°C or higher. The glass composition is effectively free of alkali metal oxides, and contains 12-25 mass% of SiO2, 10-20 mass% of B2O3 (but not as much as 20 mass%), 18-30 mass% of CaO, 15-30 mass% of MgO, and 10.5-27 mass% of BaO. When a glass powder made from the glass composition is burned at a temperature of 850 to 1050˚C to form a crystallized glass, the crystallized glass has a thermal expansion coefficient of at least 130 x 10－７/˚C at 50 to 800˚C.
