引言在X射线分析工作中,往往需要标样,用以调整仪器和校正角度。因为硅具有纯度高,化学性能稳定,易获得,且有一般衍射强度背底低,衍射峰明锐等特点,因此是国际上公认的通用标样。为此,我们研制了一批常规硅粉标样,简称为CSS。本文报道CSS测试结果及与其它硅粉进行一些比较。硅粉制备: 为防止N型,P型掺杂元素对硅粉的点 Introduction X-ray analysis often requires standard samples to adjust the instrument and correct the angle. Because of its high purity, stable chemical properties, easy availability, low back-light diffraction intensity and sharp diffraction peak, Si is internationally recognized as a universal standard. To this end, we developed a number of conventional silicon powder standard, referred to as CSS. This article reports the CSS test results and some comparisons with other silicon powders. Preparation of silicon powder: To prevent N-type, P-type doping elements on the point of silicon powder
