Abstract
A process for the production of an optically selective coating of a receiver substrate of a suitable material for solar receiver devices particularly suitable for operating at high temperatures, more specifically for receiver tubes of linear parabolic trough, which comprises: deposition of a layer reflecting infrared radiation consisting of a high-melting metal on a heated receiver substrate of a suitable material; annealing under the same temperature and pressure conditions as the deposition of the reflecting layer; deposition on the high-melting metal of one or more layers of metal-ceramic composite materials (CERMET), wherein the metal is W and the ceramic matrix is YPSZ (“Yttria-Partially Stabilized Zirconia”); deposition on the cermet of an antireflection layer; annealing under the same temperature and pressure conditions as the depositions of the cermet and antireflection layers.
