摘要
利用氧氮分析仪 ,建立了钒氮合金 (NV)中高含量氮的脉冲加热 -热导分析法。测定范围 :w (N ) =1 0 0 %～40 0 0 % ,相对标准偏差 0 61%。方法简便、快速、准确 。
High content nitrogen in vanadium-nitrogen alloy has been determined by impulse-heating thermal conductivity using LECO TC-600 nitrogen/oxygen determinator.Determination range was 1.00%-40.00%.RSD≤1%.The method is simple,quick and accuracy.It has been applied to the pratical analysis with satisfactory results.
