A X-ray diffractometer operates by directing a beam of X-rays onto a specimen, where the X-rays interact with atoms in the sample to generate diffraction. Diffraction patterns are formed when X-rays match integer multiples of the atomic spacing in the sample, resulting in a series of diffraction peaks. Through analyzing the position, intensity and shape of these diffraction peaks, we can deduce the crystal structure and phase composition of the specimen.
Characteristics of X-ray diffractometer
