1. Purpose
X-Ray Diffraction (XRD) is a method in materials science used to determine the atomic and molecular structure of a crystal, as the beam of incident X-rays diffract in many directions due to the crystalline structure of the material. The purpose of this experiment is to obtain an understanding of the characteristics and the principle of Bragg’s law, observe the relationship between Bragg’s law and the lattice structures and get to learn how to operate the XRD equipment. In order to accurately find out the information on the unknown two samples provided for this experiment, the peak values found from the JCPDS card were analyzed.
2. Theory
When X-rays are irradiated to crystals, some of them undergo diffraction, and their diffraction angles and intensities are unique for each substance. The components of the unknown arbitrary sample can be identified by comparing its diffraction patterns with diffraction patterns obtained from a known material.
