Green thermo-absorbent glass

摘要

A Green thermo-absorbent glass which includes a basic composition of lime glass, which consists essentially, by weight, of: 0.86 to 0.91% of total iron expressed as Fe2O3; 23.5 to 26% of Fe-2 and 0.202 to 0.237% of FeO, expressed as Fe2O3; a critical amount of 0.15 to 0.18% of SO3 which does not affects the refining properties and ability of the SO3 to eliminate bubbles, and in the absence of CeO2; the green glass having a visible light transmission greater than 70%, an ultra-violet radiation transmission greater than 38% and less than 40%, an infra-red radiation transmission greater than 21% and less than 26.5%. and a total solar transmission greater than 41 and less than 47%, without affecting the refining properties and ability of the SO3 to eliminate bubbles.
