由北京市太阳能研究所研制的“氮氧化铝高温太阳能选择性吸收材料”于1991年10月30日通过技术鉴定。它的研制成功为太阳能集热器提高工作温度创造了有利条件。使用这种材料的真空管集热器,热效率高,应用面广。这种高温选择性吸收材料采用单靶金属铝磁控反应溅射沉积技术制成,基体材料为光亮铝(或铜)。它具有良好的光学性能、热稳定性能和抗紫 Developed by the Beijing Institute of Solar Energy “nitrogen aluminum oxide high temperature solar selective absorption material” in October 30, 1991 through technical appraisal. Its successful development of solar collectors to improve the working temperature has created favorable conditions. The use of such materials, vacuum tube collectors, thermal efficiency, wide range of applications. This high temperature selective absorbing material is made using single-target metallic aluminum magnetron reactive sputtering deposition technology, with the substrate material being bright aluminum (or copper). It has good optical properties, thermal stability and anti-purple
