摘　　要：以普通陶瓷毛胚为基底，采用钒钛磁铁矿渣制备黑釉吸收层，并采用红外灯辅助喷雾热解法制备锑掺杂氧化锡薄膜作为红外反射层，构建结构简单的陶瓷表面太阳选择性吸收涂层，并对涂层微结构和性能进行表征，结果表明-掺锑氧化锡薄膜结晶完全，厚度均一；涂层太阳吸收比可达0．93，法向发射比低于0．25；经500h的老化性试验后，涂层的太阳吸收比和法向发射比变化小于10％。With the common used ceramic as the substrate, the black ceramic from vanadium titanomagnetite slag as the light absorber, and Sb-doped SnO2 （ATO） thin film as the infrared-reflective layers, we fabricated a novel solar selective absorbing coating on ceramic via infrared lamb-assisted spray pyrolysis. The morphology and light absorption properties of the coatings were systematically investigated, which revealed that the ATO thin film has a high crystallinity and uniform thickness. The solar absorptance of the selective absorbing coating was above 0.93, the normal thermal emittance was lower than 0.25, and the variety rate was below 10% after 500 h aging test.
