WIPO Patent Application WO/2016/084627
Kind Code:
A1
Abstract:
The present invention addresses the technical problem of devising a glass powder and a composite powder which soften and become fluid at a low temperature, have a low coefficient of thermal expansion, and exhibit high water resistance and acid resistance. This glass powder is characterized by having a glass composition that contains, in terms of mol.%, 48-75% of SiO2, 5-23% of B2O3, 5-25% of Al2O3, 5-30% of Li2O, and 0-25% of ZnO, with the SiO2/B2O3 molar ratio being 3.23 or higher.
