Abstract

Procedimiento de obtención de una sustancia luminiscente emisora de color rojo revestida con pigmento rojo para tubos de imagen en color, caracterizado porque comprende revestir un cuerpo luminiscente a base de elementos de tierras raras, activado por europio, con un compuesto compelo que contiene sulfuro de indio y un sulfuro de metal alcalino, seguido por cochuración del cuerpo luminiscente revestido, a una temperatura de 400 a 600ºC, para convertir el compuesto complejo en un pigmento rojo consistente en sulfuro de indio y un sulfato de metal alcalino.
