摘要 |
An ultraviolet/infrared absorbent low transmittance glass consists of base glass, and colorants. The base glass comprises 65 to 80 wt. % SiO2; 0 to 5 wt. % Al2O3; greater than 2 to less than or equal to 10 wt. % MgO; 5 to 15 wt. % CaO wherein a total amount of MgO and CaO is 7 to 15 wt. %; 10 to 18 wt. % Na2O; 0 to 5 wt. % K2O wherein a total amount of Na2O and K2O is 10 to 20 wt. %; and 0 to 5 wt. % B2O3. The colorants without Se is formed of 1.25 to 2.2 wt. % total iron oxide (T-Fe2O3) expressed as Fe2O3; 0.001 to 0.03 wt. % CoO; and 0.003 to 0.2 wt. % NiO. The glass has a turquoise blue or deep green color, and exhibits low or middle visible light transmittance, low total solar energy transmittance and low ultraviolet transmittance.
