Abstract (en)
The present invention relates to a method of controlling an atmosphere in a furnace, particularly for performing a sintering process, wherein a dew point and/or a redox potential and/or a material concentration, particularly a mass fraction and/or a mole fraction and/or a volume concentration in the furnace is determined, wherein a base atmosphere comprising nitrogen and hydrogen is provided (201) in the furnace, wherein a fraction of hydrogen of the base atmosphere is predetermined (201) in dependence of a material to be sintered in the furnace, wherein an additional amount of hydrogen is provided (203) in the furnace in dependence of the determined dew point and/or the determined redox potential and/or the determined material concentration in the furnace, wherein an amount of a carbon potential enrichment gas and/or an amount of a carbon potential decreasing gas is provided (205) in the furnace in dependence of the determined dew point and/or the determined redox potential and/or the determined material concentration in the furnace.
