Abstract
A glass composition with low thermal radiative conductivity at high temperature has the following components in weight percentage, expressed with respect to the total weight of the glass composition: SiO2 50-85%; Al2O3 0-30%, B2O3 0-20%; Na2O 0-25%; CaO 0-25%; MgO 0-15%; K2O 0-20%; BaO 0-20%; Fe2O3 total 0.002-0.1%. The glass also includes NiO at a level of 0.0001% to 0.0020% by weight of the total glass composition.
