Title:
GLASS PLATE HAVING UV RESISTANCE
Document Type and Number:
WIPO Patent Application WO/2017/038621
Kind Code:
A1
Abstract:
The objective of the present invention is to provide a high-strength glass plate having UV resistance, which maintains the high strength without being decreased in the transmittance in a specific wavelength range even if irradiated with short wavelength UV. The present invention relates to a glass plate for UV irradiation, which contains, in mass%, 60-75% of SiO2, 2-25% of Al2O3, 10-20% of Na2O, 0-7% of K2O, 0.5-10% of MgO, 0-15% of CaO and 0.035-0.12% of Fe2O3, and which has a redox ratio of less than 0.550 and a CaO/MgO (mass ratio) of 1.5 or less.
