Abstract
Procedimiento de fabricación de un ánodo inerte de cermet NiO-NiFe2O4-M que comprende la preparación de una mezcla inicial que comprende los precursores de la fase cerámica mixta y de la fase metálica y un ligante orgánico, una conformación de la mezcla para formar una pieza cruda de forma determinada y una operación de sinterización de la pieza cruda a una temperatura típicamente superior a los 900° C en atmósfera controlada. La proporción de ligante orgánico en la mezcla inicial es inferior a 2,0 % en peso y el precursor de la fase metálica comprende un polvo metálico que contiene cobre y níquel. Este procedimiento permite reducir las emisiones de materias volátiles tóxicas con un pequeno aporte de oxígeno, reducir el tiempo de eliminación del ligante y limitar los riesgos de fisuración y producción de porosidad asociados a la eliminación del ligante en fase gaseosa en el ánodo de importantes dimensiones.Method of manufacturing an inert anode of cermet NiO-NiFe2O4-M comprising the preparation of an initial mixture comprising the precursors of the mixed ceramic phase and the metallic phase and an organic binder, a conformation of the mixture to form a piece Crude in a certain way and a sintering operation of the raw part at a temperature typically higher than 900 ° C in a controlled atmosphere. The proportion of organic binder in the initial mixture is less than 2.0% by weight and the metal phase precursor comprises a metal powder containing copper and nickel. This procedure makes it possible to reduce the emissions of toxic volatile materials with a small oxygen supply, reduce the elimination time of the binder and limit the risks of cracking and production of porosity associated with the elimination of the gaseous phase binder in the anode of important dimensions.
