Abstract

Procedimiento para la fabricación de capas absorbentes selectivas de alta capacidad de absorción y baja emisión, en especial para colectores solares, caracterizado porque la superficie del absorbedor, consistente en un metal formador de un óxido negro o que tiene una capa de cubierta a base de dicho metal, es transformada en el óxido negro por oxidación electrolítica en solución alcalina a temperatura ambiente o un poco superior a ella.
