标准摘要
[中文适用范围]： 本文件规定了使用布拉格-布伦塔诺衍射仪通过X射线衍射（XRD）在质量分数范围为0.3%至5.0%内对硅砖中残余石英（即α-石英）进行定量分析的方法。本文件包括样品制备和使用外部标准初步建立工作曲线的详细步骤。 本文件未解决与其使用相关的安全问题。测试过程中长时间或反复吸入硅砖粉末和参考材料可能对肺部造成损害。用户有责任建立适当的安全和健康实践。 [外文原描述]： This document specifies a method for the quantitative analysis of residual quartz (i.e. alpha-quartz) in silica bricks within the mass fraction range of 0,3 % to 5,0 %, by X-ray diffraction (XRD) using a Bragg-Brentano diffractometer. This document includes details of sample preparation and of preliminary establishment of a working curve using external standards. This document does not address the safety issues associated with its use. The ground silica brick powders and reference materials may cause damage to lungs through prolonged or repeat inhalation during tests. It is responsibility of the users of this standard to establish appropriate safety and health practices.
英文名称Phase quantitative analysis of residual quartz in silica bricks — X-ray diffraction method
