Abstract

UN PROCESO PARA PRODUCIR METAL REFRACTERIO ESFERICO DIVIDIDO FINALMENTE VASADO EN POLVOS, COMPRENDE EL FORMAR UNA SOLUCION ACUOSA QUE CONTENGA AL MENOS UN METAL REFRACTRIO, FORMAR UN MATERIAL BASADO EN METAL REFRACTARIOREDUCIBLE SOLIDO QUE CONTENGA UN COMPONENTE SELECCIONADO DEL GRUPO CONSISTENTE EN SALES METALICAS REFRACTARIAS, OXIDOS METALICOS REFRACTARIOS, HIDROXIDOS Y MEZCLAS DE ELLOS, REDUCIENDO EL MATERIAL SOLIDO A METAL REFRACTARIO BASADO EN PARTICULAS DE POLVO, SOMETIENDO EL REFRACTARIO BASADO EN PARTICULAS DE POLVO A UNA ZONA DE GRAN TEMPERATURA PARA DERRETIR UNA PARTE DE LAS PARTICULAS Y ENFRIANDO EL MATERIAL DERRETIDO PARA FORMAR METAL REFRACTARIO ESFERICO ESENCIALMENTE BASADO EN PARTICULAS DE POLVO.
