Title:
GLASS COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2019/082590
Kind Code:
A1
Abstract:
This glass composition contains SiO2, B2O3, Al2O3, an oxide of an alkaline earth metal and another metal oxide. If CTE(T) denotes the average coefficient of thermal expansion of the glass composition within the temperature range 0ºC to TºC, the relationship (17.1×10-3×T+25.4)×10-7/ºC ≤ CTE(T) ≤ (17.1×10-3×T+31.4)×10-7/ºC is satisfied within the temperature range 0-100°C.
