从烧坯和不同厚度的轧制板坯取样,使用辉光放电质谱法检测元素含量,辉光放电质谱法为半定量分析,纯度单位为ppm,用100%减去已测金属元素,得到高纯铼样品的纯度。
Samples are taken from the sintered slab and rolled slabs of different thicknesses. Glow discharge mass spectrometry is used to detect element content. Glow discharge mass spectrometry is a semi-quantitative analysis. The purity unit is ppm. Subtract the measured metal elements from 100% to obtain high The purity of the pure rhenium sample.
