AbstractAbstract
[en] Physical concentrating of niobium impurities by the evaporation method has been used while analyzing niobium compounds of high purity. Metal niobium and its salts have been preliminary transformed into niobium pentoxide. Impurities have been evaporated at 1800-19O0 deg C in the presence of sodium chloride. The analytical lines of the elements being determined and the limits of their detection are presented. The relative standard deviations vary from 0.1 to 0.25 depending on the impurity element
