Abstract
SE FORMA UN ARCO ENTRE UN ELECTRODO MOVIL (E) (PREFERIBLEMENTE DE GRAFITO) Y UN ELECTRODO FIJO (7) EN UN HORNO CUANDO SE FUNDEN LOS OXIDOS DE METAL USANDO UN PLASMA. EL GAS, POR EJ. NITROGENO, SE INTRODUCE DENTRO DE LA CAVIDAD (P) ALREDEDOR DEL ELECTRODO MOVIL (E) PARA EVITAR QUE EL VAPOR DE METAL SE ASIENTE SOBRE EL RECUBRIMIENTO INTERIOR (3; 9) DEL HORNO (1). EL ELECTRODO MOVIL PUEDE CONECTARSE A UN MASTIL (30) SOBRE EL TECHO DEL HORNO (4) PARA ALINEAR EL ELECTRODO EN SU CAMINO A TRAVES DEL AGUJERO (10) EN EL TECHO HACIA EL INTERIOR DE LA CAMARA (C) DEL HORNO.
