Abstract

METODO PARA PREPARAR UN ALUMINATO DE METAL ALCALINO-TERREO LUMINISCENTE, ACTIVADO CON EUROPIO BIVALENTE O CON PLOMO BIVALENTE.CONSISTE EN PREPARAR UNA MEZCLA DE OXIDO DE ESTRONCIO, DEL QUE HASTA UN 25 EN MOLES PUEDE ESTAR REEMPLAZADO POR OXIDO DE CALCIO, OXIDO DE ALUMINIO, OXIDO DE EUROPIO U OXIDO DE PLOMO, O DE COMPUESTOS ESTOS OXIDOS POR CALENTAMIENTO, ELIGIENDOSE LA PROPORCION MOLAR DE METAL BIVALENTE TOTAL A ALUMINIO DESDE 1:2 A 1:5. LA MEZCLA FORMADA SE CALIENTA A UNA TEMPERATURA COMPRENDIDA ENTRE 1.100 Y 1.500 GRADOS PARA OBTENER UN ALUMINATO CON UNA ESTRUCTURA CRISTALINAADECUADA.DE APLICACION EN LA PREPARACION DE PANTALLAS LUMINISCENTES Y DE LAMPARAS DE DESCARGA DE VAPOR DE MERCURIO, A BAJA PRESION.
