【Abstract】 The development of spectral reference material of nuclear grade zirconium alloys was introduced. Spectroscopic reference material of nuclear grade zirconium alloys was prepared by the process of nuclear grade sponge zirconium preparation, three times vacuum consumable arc furnace melting and forging. The uniformity and stability of the prepared reference material were tested by inductively coupled plasma emission spectrometry, spectrophotometry and inductively coupled plasma mass spectrometry, and the uncertainty of the fixed value was evaluated. The reference material of nuclear grade zirconium alloy was determined by a joint setting method, and the standard mass fraction values of Cr,Al,Fe and Ni were determined. The mass fraction values were 0.008 9%-0.010 9%,0.0 022%-0.003 6%, 0.052 3%-0.056 1%, 0.000 09%-0.000 19%, respectively. The reference material has the advantages of uniform composition,good stability and accurate value, which can be used for the analysis and detection of alloy and impurity elements in zirconium alloy.更多还原
