紫外线吸收性玻璃
摘要：
本发明涉及紫外线吸收性玻璃。本发明提供一种适合作为深灰色玻璃的、在具有极低的紫外线透射率的同时具有较低的可见光透射率、良好的熔化性，并且原料成本低的紫外线吸收性玻璃。一种紫外线吸收性玻璃，其中，板厚2.8mm时的所述紫外线吸收性玻璃的、基于标准A光源的可见光透射率(TVA)为8％～25％，并且板厚2.8mm时的、所述紫外线吸收性玻璃的由ISO13837：2008约定A规定的紫外线透射率(TUV400)为2.0％以下。
摘要（英）：

The present invention provides an ultraviolet absorbing glass that is suitable as dark grey glass and has an extremely low ultraviolet transmittance, and at the same time has a low visible light transmittance and favorable solubility, and is low in raw material costs. The ultraviolet absorbing glass has a visible light transmittance (TVA) based on a standard illuminant A at a sheet thickness of 2.8 mm being 8% to 25%, and has an ultraviolet transmittance (TUV400) defined by ISO 13837:2008 convention A at a sheet thickness of 2.8 mm being 2.0% or less.
