powder diffraction standards

Powder diffraction standards are calibrated materials used in X-ray diffraction (XRD) to assess and ensure the accuracy of measurements. When scientists analyze the structure of powdered materials, these standards provide reference patterns that act like a 'map' for identifying and comparing the positions of peaks in the diffraction pattern. By using known standards, researchers can verify that their XRD equipment is functioning correctly and can reliably interpret the results of their sample analysis, leading to more accurate identification of materials and their properties.
