Abstract
The results of experiments that measure the spectral emittance ελ (hence absorptance) at 3.8‐μ wavelength for 6061 aluminum alloy and 9606 pyroceram at elevated temperatures are reported. ελ for 6061 aluminum was measured within the molten state over the surface temperature range of 1200–2100 °F. For 9606 pyroceram, ελ was measured between 1000 and 2000 °F. The data shows that for aluminum, ελ increases linearly with temperature from 0.138 at 1200 °F to 0.190 at 2100 °F. For pyroceram, ελ has an initial value of 0.91 at 1000 °F and slowly decreases to 0.68 at 2000 °F.Keywords
