High temperature solar absorber coating and method of applying same
First Claim
Patent Images
1. A composition capable of forming solar absorbing coating having a solar absorptance greater than 0.90 on solar absorbers for solar collectors of the type operable at temperatures above 550°
- F. comprising;
an optical filler and a binder in the weight ratio ranging from about 1 to 1 to about 3 to 1, said optical filler having a particle size in the range of from about -100 mesh to about -325 mesh, said optical filler being an inorganic oxide which is thermally stable at operating temperatures above 550°
F. and which has a solar absorptance greater than about 0.90 at wavelengths of from about 0.35 microns to about 3.0 microns, said inorganic oxide being selected from the group consisting of ferrites, oxides of nickel, cobalt, iron, molybdenum and strontium and mixtures thereof, said binder being an alkyl polysilicate.

Abstract
Improved coatings for high temperature solar collectors comprise thermally stable inorganic oxides selected from ferrites, metal oxides and mixtures thereof having solar absorptances greater than 0.9 at wavelengths ranging from about 0.35 to 3.0 microns. The coatings can be applied to a heat transfer surface by painting an organic silicate dispersion of the optically active material onto the substrate and thereafter curing the silicate binder.
