Abstract
ESTE PROCESO CONSISTE, DESPUES DE HABER COLOCADO LOS DIFERENTES METALES ESCOGIDOS EN UN CRISOL (1C), EN PROVOCAR LA FUSION DE DICHOS METALES BAJO ATMOSFERA NEUTRA O REDUCTORA QUE ASEGURA UNA MEZCLA DEL LIQUIDO EN VISTA DE HOMOGENEIZARLO, EN RECUPERAR LA ALEACION LIQUIDA, EN PULVERIZAR LA ALEACION OBTENIDA BAJO FORMA DE POLVO DE GRANULOMETRIA DETERMINADA EN DONDE CADA UNA DE LAS PARTICULAS ES HOMOGENEA Y EN OXIDAR DICHAS PARTICULAS. SE APLICA PARA LA FABRICACION DE CERAMICAS SEMICONDUCTORAS DEL TIPO VARISTORES A BASE DE OXIDO DE CINC ASI COMO PARA LA FABRICACION DE PRODUCTOS SUPERCONDUCTORES O DE TERMISTORES DE COEFICIENTE TERMICO POSITIVO O NEGATIVO.
