THE TOTAL ASSAY OF HIGH PURITY NIOBIUM METAL BY DIFFERENTIAL SPECTROPHOTOMETRY
Technical Report
·
OSTI ID:4281135
A method was developed to determine the total niobium content of high- purity niobium metal. Samples are dissolved in hydrofluoric and nitric acids and fumed with sulfuric acid. Niobiumis determined by differential spectrophotometric measurement of the peroxyniobate complex formed in a mixture of phosphoric and sulfuric acids. The method as written covers a concentration range at 92.3 to 100.0% niobium. The relative standard deviation of the method is about plus or minus 0.1%. (auth)
