WIPO Patent Application WO/2010/084925
Kind Code:
A1
Abstract:
Provided is a glass composition which has a high refractive index, low-temperature softening properties and a low thermal expansion coefficient, and a member which has said composition on a substrate. The glass composition is characterized in having a refractive index (nd) of 1.88‑2.20, a glass transition temperature (Tg) of 450‑490°C, and an average thermal expansion coefficient (α50-300) of 60 × 10-7/K to 90 × 10-7/K at 50‑300°C. The content of Bi2O3 content is 5‑25%, represented in mol% based on oxide.
