Abstract

PROCEDIMINETO PARA PRODUCIR CIRCONIO PURIFICADO COCIENDO UNA ESPONJA DESTILADA DE CIRCONIO DURANTE MEDIA HORA POR LO MENOS DE 120-400 GRADOS CENTIGRADOS Y FUNDIENDO DESPUES POR HAZ DE ELECTRONES LA ESPONJA COCIDA AL VACIO, PREFERIBLEMENTE EN UN HORNO DE HAZ DE ELECTRONES DE BARRIDO MULTIPLE. ES PREFERIBLE USAR UN HORNO DE HAZ DE ELECTRONES DEL TIPO DE AVANCE GIRATORIO, DE MODO QUE LA ESPONJA PUEDA COCERSE Y FUNDIRSE SIN CONSOLIDARLA EN UN ELECTRODO. TAMBIEN ES CONVENIENTE ENSAYAR LA ESPONJA, Y RECHAZARLA SI TIENE MAS NIVEL DE OXIGENO QUE EL DESEADO Y SELECCIONAR SOLO LA QUE TENGA MENOS OXIGENO PARA USARLA COMO ESPONJA DESTILADA PARA SER COCIDA Y FUNDIDA POR HAZ DE ELECTRONES.
