Abstract (en)

[origin: WO2009107157A2] A surface-coating material for receiver tubes of solar plants, in particular of the type with linear parabolic mirrors, constituted by a multilayer structure comprising a bottom metal layer (back reflector) highly reflective in the infrared and a top layer of anti-reflective material, provided between which is a layer of an innovative composite ceramic-metal material (CERMET) of the graded type, in the case in point with volumetric fraction of metal that decreases, passing from the metal reflector to the anti-reflective layer. In particular : i) the ceramic matrix of the CERMET is made up of aluminium oxide (AI2O3), whilst the metal particles dispersed in the ceramic matrix are constituted by tungsten (W); ii) the back reflector is tungsten in its crystalline form a; iii) the anti-reflective layer is aluminium oxide or else silicon oxide.
