A New Method to Analyze Nitrogen Content of VN Alloy

Methods to analyze the nitrogen content of vanadium-nitrogen alloy were discussed with ON2008 oxygen and nitrogen analyzer(made in China).Referred to the reported documents,a new simplified method was presented.The new method chose argon as the carrying gas,no flux is needed,the sample is directly put into the crucible,and a graphite cover designed specially is used.The new method cut down the analyzing cost and simplifies the preparation of sample,the weighing of sample could be more than 0.1 g.The method was applied in the analysis of VN production,and the accuracy of result could match the requirement.
