Chris Stanton May 3, 2007 Chemistry 216 X – Ray Diffraction I. Introduction This lab allows for the use of x-ray diffraction to determine both the x-ray powder pattern of a substance and the precise structure of the material. The planes, called Bragg planes, within the atom can diffract the x-rays. Different atom sizes and packing arrangements within the atom can produce different types of Bragg planes. This lab uses a prepared (crushed) crystalline solid to create x-ray powder diffraction for a group of materials. The different solids used in this lab were lithium chloride, molybdenum, potassium bromide, and cesium chloride. II. Experimental Procedure 1. Thoroughly grind your samples in a clean, dry mortar. 2. Take the sample to the lab where the diffractometer is located and place it in the sample holder. 3. Your TA or another instructor will guide you through the process of using the diffractometer. 4.
