Abstract

FABRICACION DE VIDRIOS FOTOCROMATICOS TRANSPARENTES Y ESENCIALMENTE INCOLOROS, QUE SE OSCURECEN HASTA ADQUIRIR UN MATIZ MARRON CUANDO SE EXPONEN A LOS RAYOS ACTINICOS Y QUE RECUPERAN SU ASPECTO INCOLORO CUANDO DEJAN DE ESTAR SOMETIDOS A DICHA RADIACION. LOS CONSTITUYENTES EMPLEADOS EN LA FABRICACION DEL VIDRIO FOTOCROMATICO, EXPRESADOS EN PORCENTAJE EN PESO SOBRE LA BASE DE OXIDO, SON: DE 40 AL 76% DE SIO ; DE 4 AL 26% DE AL O ; DE 4 AL 26% DE B O ; POR LO MENOS UN OXIDO DE METAL ALCALINO EN LA PROPORCION DE 2 AL 8% DE LI O, DE 4 AL 15% DE NA O, DE 4 AL 15% DE K O, DE 8 AL 25% DE RB O Y DE 10 AL 30% DE CS O; POR LO MENOS UN HALOGENO EN LA PROPORCION DE 0,2% DE CLORO, 0,1% DE BROMO Y 0,08% DE YODO; Y DE UN MINIMO DE PLATA QUE VARIA SEGUN EL CONTENIDO DE HALOGENO. >DE APLICACION EN LA FABRICACION DE LENTES OFTALMOLOGICAS.
