SELEKTIVT SOLVARME-ABSORBERENDE MATERIALE OG FREMGANGSMAATE FOR FREMSTILLING AV DETTE.

摘要

An object of this invention is to provide a solar heat selective absorbing material of high performance which is prepared by using a diversity substrate by simple manufacturing methods. The construction of the solar heat selective absorbing material is such that a carbide of a transition metal belonging to the IV group of periodic table or a mixed powder of the carbide and the aluminum is applied directly or by means of a binder on the surface of the substrate to form a film. This solar heat selective absorbing material is manufactured by a method of forming a film of material, for example, ZrC on the surface of the substrate by high frequency sputtering or a method of mixing a mixed powder of the ZrC and Al with a resin binder and coating or printing the mixed material on the surface of the substrate.
