    • The present invention relates to a dark neutral green gray soda-lime glass composition comprising, as a colorant ingredient per 100 weight parts of a base glass composition, 1.4 to 2.5 weight parts of total Fe 2 O 3 , 0.02 to 0.04 weight parts of CoO, 0.0001 to 0.004 weight parts of Se, 0.005 to 0.5 weight parts of MnO 2 , and 0.05 to 1 weight parts of CeO 2 . The glass composition of the present invention has a visible light transmittance (LT A ) of 15% or less, an ultraviolet ray transmittance (T uv ) of 0 to 1%, and a solar transmittance (T sol ) of 15% or less, measured for a reference thickness of 4mm. As described above, the glass composition of the present invention is excellent in absorbing ultraviolet rays and solar heat, and therefore can be valuably used in privacy glass or a sunroof of a motor vehicle, or in glass used for construction.
    • 本发明涉及一种深色中性绿灰色钠钙玻璃组合物,其包含作为着色剂成分的每100重量份基础玻璃组合物包含1.4-2.5重量份的全部Fe 2 O 3,0.02-0.04重量份的CoO,0.0001至 0.004重量份的Se,0.005-0.5重量份的MnO2和0.05-1重量份的CeO2。 本发明的玻璃组合物的可见光透过率(LTA)为15%以下,紫外线透过率(Tuv)为0〜1%,太阳光透射率(Tsol)为15% 参考厚度4mm。 如上所述,本发明的玻璃组合物吸收紫外线和太阳能热量优异,因此可以有效地用于汽车的隐私玻璃或天窗,或用于建筑用玻璃。
