三硫化二钆的国家标准
目前,我国尚未出台关于三硫化二钆的国家标准,但可以参考国际标准。以下是一些相关的国际标准:
1. ISO 12698-1:1996 Chemical analysis methods of rare earth impurities in rare earth metals and their oxides - Part 1: Determination of rare earth impurities in gadolinium metal by spectrochemical method
2. ASTM B 995-20 Standard Specification for Uranium Hexafluoride for Enrichment
3. ASTM B 350-20 Standard Specification for Zirconium and Zirconium Alloy Ingots for Nuclear Application
4. ASTM C 698-20 Standard Test Methods for Chemical, Mass Spectrometric, and Spectrochemical Analysis of Nuclear-Grade Mixed Oxides ((U, Pu)O2)
这些标准主要涉及到三硫化二钆的化学分析方法、原材料和产品的规格要求等内容,对于三硫化二钆的生产和质量控制具有重要的指导作用。
