Document Type and Number:
WIPO Patent Application WO/2018/066635
Kind Code:
A1
Abstract:
Disclosed is a glass composition for sealing which, by being fired in the form of a powder at a temperature of 900-1150°C, becomes crystallized glass exhibiting a thermal expansion coefficient of 80-110 × 10-7/°C at 50-850°C. The composition contains substantially no boron oxide or barium oxide, but contains 43-53 mol% of SiO2, 12-33 mol% of CaO, 12-33 mol% of MgO, 1-7 mol% of La2O3, and 0-4.5 mol% of ZnO.
