Abstract
Five composite materials of Al-N have been prepared by dc magnetron reactive sputtering techniques. Good agreement is obtained between computed and experimentily measured reflec-tances and absorptances for Al-N/Al(AD). Solar absorptance of Al-N/A1 selective surface(HT) is - 0.92 and emittance - 0.04 at room temperature. Gas evolution from sputtered Al-N/Al has been studied using thermomanometry and mass spectrometry. The total outgassing from the surface is considerably low.
