Essay / X-ray diffraction (XRD) and its significance for the medical world...
X-ray diffraction (XRD) is an analytical method that provides information on the intensity of X-rays in relation to the angle of diffusion of the substance. . This characteristic is unique for each material. Therefore, one can identify the unknown material by comparing the XRD pattern with the standard XRD pattern3. For the standard, the crystal phases and diffraction pattern of approximately 50,000 inorganic and 25,000 organic single components are collected and stored on a magnetic medium 5. The history of X-ray diffraction begins in the early 20th century. At the time, it was strongly believed that crystals contained many repeating blocks and that each repeating unit consisted of a constant number. This concept can be proven using density, atomic numbers and Avogadro's number 1. The X-ray diffraction experiment is carried out by Friedrich and Knipping for the first time using a copper sulfate crystal. Performing the experiment, they collected the diffraction pattern of the crystal and declared that the x-rays must be electromagnetic radiation 2. In 1912, William Lawrence Bragg and his fa...
