A method was developed for the determination of niobium content in armor materials by ICP-AES. Sample was digested with hydrochloric acid-nitric acid-hydrofluoric acid by microwave,the detector was CID solid-state detector with the detection wavelength of 309.417 nm. Under the selected conditions of determination, the linear range of curve was 0.005%-1.0%, the linear correlation coefficient was 0.999 7. The detection limit was 0.000 68%. The relative standard deviation of determination results was not more than 3%(n=10), and the standard addition recovery rate was 96.0%-98.7%. The method is simple in operati on and measurement results are accurate and reliable. It can be used for the determination of niobium content in the armor materials.
