Abstract
Mejoras en la patente principal nº 464.074 por procedimiento para obtener sobre aluminio una superficie de color oscuro para la absorción selectiva de rayos solares, en virtud del cual se procede a oxidar aluminio por vía química en una primera etapa, lo más brevemente posible, mediante baño de cromatización alcalino, ennegreciéndose la capa de oxido así obtenida en una segunda etapa mediante una solución caliente consistente en permanganato potásico y nitrato de cobalto o respectivamente nitrato de cobre, caracterizándose las mejoras en que la segunda etapa se divide en dos baños, para lo cual se hace actuar primeramente el permaganato potásico, eventualmente con ácido nítrico, y después el nitrato de cobalto o respectivamente el nitrato de cobre.
