我们在熔融浇注法制备荧光x射线分析试样的基础上,参阅了有关文献报导,对加入某些添加剂的熔融直接剥离制样技术进行了系统的研究。从而确立了添加少量NaBr的熔融直接剥离制样方法。该法不仅提高了制样速度,而且对改善分析精度和准确度均有显著效果。适用范围:耐火材料原料、制品以及矿物、矿石、金属氧化物等试样的荧光x射线分析。 (一)设备、试剂及标样东德蔡氏(Zeiss)VRA2型荧光x射线分析谱仪。马弗炉(最高温度1300℃、功率5千
On the basis of the preparation of fluorescent X-ray analysis samples by melt casting method, we refer to the literature reports, and systematically studied the melt direct peeling sample preparation technology by adding some additives. Thus, a sample preparation method of melt direct stripping with a small amount of NaBr was established. The method not only improves the sample preparation speed, but also has a significant effect on improving the analysis accuracy and accuracy. Scope: Refractory materials, products and minerals, minerals, metal oxides and other samples of the fluorescence X-ray analysis.
