Abstract
The effect of doping with SrSiO 3 in the range of 1 to 17.5 mass % on the reflectance spectra and integral solar ahsorptance factor of ZrO 2 powders and their stability at ultraviolet irradiation were investigated. It wasfounded that the powders doped with 1 mass % of SrSiO 3 possess the greater photostability. Two types of thermal control coatings were fabricated. The first one was based on the undoped ZrO 2 pigment and the second one was based on the ZrO 2 pigment doped by 1 mass % of SrSiO 3 . The comparative investigations of their optical properties and photostability show that the coating based on doped pigment is more effective than the coating with undoped pigment. The prediction of optical properties degradation for these coatings was made for a lifetime of 10 years according to obtained data. This prediction may be used for altitudes of 600-800 km, for which the main damaging factor is ultraviolet radiation of the sun.
