Abstract

CONSTA DE LAS SIGUIENTES ETAPAS: 1) ADICION AL BAÑO, QUE ESTA A UNA TEMPERATURA TAL QUE SU TENSION DE VAPOR ES AL MENOS DE 1 MM. DE MERCURIO, DE UN FLUIDO CRIOGENICO EN FASE LIQUIDA CONSTITUIDO POR NITROGENO. 2) EVACUACION FUERA DEL RECINTO DEL LIQUIDO CRIOGENICO QUE CONTIENE EN SUSPENSION LAS PARTICULAS SOLIDAS. 3) SEPARACION DE LAS PARTICULAS DEL FLUIDO, RECOGIENDOLAS PARA OBTENER EL POLVO. LA SEPARACION DE PARTICULAS Y SU RECOGIDA SE HACE POR FILTRACION. EL MATERIAL METALICO ESTA CONSTITUIDO POR UNA ALEACION DE CU-ZU CON 30 POR 100 DE ZU; DICHA ALEACION ES PUESTA A 1065ºC.
