Abstract
A Method was studied for determination of oxygen and nitrogen in Zr-based amorphous alloy by inert gas fusion-infrared absorption/thermal conductivity method, the optimum conditions were determined by experiments on the parameters such as crucible, sample weight and analysis power. When zirconium-based amorphous alloy is melted by heated crucible, the sample weight ranges between 0.07 g∼0.08 g, with analysis power is 6.0 KW; results will be stable and reliable. The relative standard deviation of the accuracy was between 1.13% and 3.47%, the relative standard deviation of the precision was between 0.67% and 4.92%. This method is quick and convenient, and the results are accurate and reliable, it can guarantee the quantitative determination of oxygen and nitrogen element in Zr-based amorphous alloy and guide the scientific research and production activities.
