Spectroelectrochemistry studies in niobium-containing chloride melts

S Spectroelectrochemistry studies in niobium-containing chloride melts 

In a special series of experiments the spectroelectrochemical method was applied to study niobium speciation in chloride melts. An equimolar mixture of sodium and potassium chlorides was chosen as solvent because of its higher technological significance for niobium elecfiorefining. 

Additional experiments are required to determine the potential range values where particular niobium oxidation state species can be stabilised.
