Abstract

PURPOSE: To manufacture a high performance solar energy absorber by the procedure in which a noncrystal metal composed mainly of Fe, Co, Ni, Cr, etc., is subjected to a specific heat treatment followed by the corrosive treatment of its surface.
CONSTITUTION: A metal comtaining 5 to 30 atom % one or two or more of elements such as B, C, P, Si, Al, S, Se, etc., and also one or two or more of metals such as Fe, Co, Ni, and Cr as the remaining components is melted together with, as needed, 2 to 40 atom% one or two or more of Cr, Cu, Mo, W, and Ti, an then cooled rapidly at a cooling rate of 105 to 106°C/sec to make more than 30 atom% of the metal noncrystal. Then, the metal is heated at a temperature above 150°C and below crystallization temperature +500°C or kept at the temperature and then cooled. And, the metal surface is corroded by using sulfuric acid, hydrofluoric acid, caustic soda, a saline water, etc., to form a finely rough surface. The metal plate is adhered to a metal plate, e.g., Al, Cu, stainless steel, etc., to obtain a solar energy absorber.
