Abstract

Abstract Translated from German Die Erfindung bezieht sich auf den Gluehprozess, der zur Herstellung von Aluminatleuchtstoffen erforderlich ist. Diese Leuchtstoffe werden bei Lampen, Katodenstrahlroehren und Roetgenschirmen eingesetzt. Ziel der Erfindung ist die Herabsetzung der Gluehtemperaturen. Erfindungsgemaess wird die Aufgabe dadurch geloest, dass die Mischung der Ausgangsstoffe bei Temperaturen zwischen 1200-1350 Grad C in einer Gluehatmosphaere, die bis zu 100 % Salzsaeuregas enthaelt, mindestens einmal geglueht wird. The invention relates to the gluing process required for the production of aluminate phosphors. These phosphors are used in lamps, cathode ray tubes and Roetgen screens. The aim of the invention is the reduction of the annealing temperatures. According to the invention, the object is achieved in that the mixture of the starting materials at temperatures between 1200-1350 degrees C in a Gluehatmosphaere containing up to 100% Salzsaeuregas, at least once is geglueht.
