Abstract

METODO DE FABRICAR UN MATERIAL LUMINISCENTE ACTIVADO POR EUROPIO BIVALENTE O POR CROMO TRIVALENTE. CONSISTE EN CALENTAR A UNA TEMPERATURA ENTRE 1056 Y 1200C, Y EN ATMOSFERA REDUCTORA CASO DE ACTUACION POR EUROPIO O EN ATMOSFERA OXIDANTE, CASO DE ACTUACION POR CROMO, A UNA MEZCLA DE PARTIDA QUE COMPRENDE OXIDOS O COMPUESTOS FORMADORES DE OXIDOS DE LOS ELEMENTOS CONSTITUYENTES, PARA FORMAR ALUMINATO Y/O GALIATO, QUE TIENE UNA ESTRUCTURA ORTORROMBICA CON UN GRUPO ESPECIAL PNNM Y UNA COMPOSICION DEFINIDA POR LA FORMULA (ME2-X A6-4 EUX CRY O11). CUANDO ME ES SR; A ES AL CON UN CONTENIDO DE 25% EN MOLES REEMPLAZADO POR GA; 0,001 X 0,25 E Y - 0; CUANDO ME ES BA; A ES GA CON UN CONTENIDO DE 25% ENMMOLES REEMPLAZADO POR AL; 0,001 Y 0,10 Y X - 0.
