Title:
GLASS FOR COATING METAL SUBSTRATE AND METAL SUBSTRATE HAVING GLASS LAYER ATTACHED THERETO
Document Type and Number:
WIPO Patent Application WO/2014/017610
Kind Code:
A1
Abstract:
Provided is a glass for coating a metal substrate. The glass exhibits high heat resistance, crystallization and metal substrate warpage are suppressed during the formation of the glass into a glass layer, and an extremely flat upper surface can be imparted to the glass layer that is obtained. Also provided is a metal substrate having a glass layer attached thereto, the metal substrate being provided with the glass layer that exhibits high heat resistance and is extremely flat, and the entire substrate body exhibiting no warpage. The glass for coating a metal substrate contains, expressed as a mass percentage in terms of the oxides, 15-60% of SiO2, 0-35% of B2O3, 0-15% of R2O (R represents at least one element selected from the group consisting of Li, Na, and K), 25-55% of R'O (R' represents at least one element selected from the group consisting of Mg, Ca, Sr, Ba and Zn), and 0.1-7% of AI2O3, and satisfies (ZnO+MgO+CaO)/(SrO+BaO)<̳0.3. The metal substrate having a glass layer attached thereto is formed using the glass for coating a metal substrate.
