What is Spectral Selectivity of Composite Enamel Coatings on 321 Stainless Steel about?

Composite porcelain-enamel coatings consisting of spinel-type transition-metal-oxide pigments embedded in a borosilicate-glass matrix were deposited on 321 stainless steel using screen-printing techniques and characterized using total reflectance over the spectral range of 200 nm to 25 mm. The composite coatings exhibited moderate spectral selectivity and excellent thermal stability at 450 1C. Solar absorptance (a) ranged from 0.82 to 0.90 and calculated thermal emittance at 500 1C (e) ranged from 0.46 to 0.79. Both depended on coating thickness and pigment volume concentrations. As an example, the highest solar selectivity was measured in a 0.9 mm coating with a and e (500 1C) being 0.82 and 0.46, respectively.
