Abstract

PURPOSE: To produce a solar heat absorbing body provided with selective absorptivity of high effieicncy by acting an aqueous silver nitriate soln. on the surface layer consisting essentially of copper provided on the surfaces of a backing material.
CONSTITUTION: Copper is oxidized on the surface layer consisting essentially of copper provided on the outside surfaces of a backing material by using an aqueous silver nitrate soln. as a treating soln. Since this treating soln. permits treatment at lower temps. as compared to the other treating soln., its workability is excellent and there are virtually no changes in the concn. of the treating soln. Since the treating temps. are low and the treating soln. can be made into lower concns., oxidation reaction progresses extremely uniformly, and the controlling of the thickness of the selective absorptive film formed is extremely easy. Next, if corrosion resistance is particularly a factor, it is preferable to coat the surface of the selective absorptive film with a film provided with water repellency or water resistance and light transmittance in a visible light region.
