A method of preparing an Alkaline Earth Metal Aluminate Luminescent Europium Activated by divalent.

摘要

Method for preparing Alkaline Earth Metal Aluminate Luminescent Europium Activated by divalent.Consists in preparing a mixture of BARIUM OXIDE, of which up to 25 mol can be replaced by STRONTIUM OXIDE and Europium oxide, alumina, or compounds that become these oxides by heating, choosing the molar ratio between the Alkaline Earth Metal and aluminium Nio, which is between 1: 2 and 1: 10.The mixture is hot in Weakly Reductive atmosphere to a temperature between 1100 and 1400 grados.de application in ultra Discharge lamps, Mercury vapor at low pressure and in obtaining Luminescent screens.
