Basic principles of X-ray diffraction: When a beam of monochromatic X ray incident to crystal, because the crystal is made up of atomic rules are arranged into a cell, the rules of the distance between the atoms and the incident X-ray wavelength with the same order of magnitude, so by the different atomic scattering X-ray mutual interference, stronger effects in some special directions X ray diffraction, the diffraction lines in the spatial distribution of location and intensity, is closely related to the crystal structure.
Clay minerals are the main body of interaction between charged particles in soil. Studies show that there are more than ten types of clay minerals, the main types are chlorite, kaolinite, illite, montmorillonite and illite/montmorillonite. The types of clay minerals are different in different areas, and their content is also very different in different areas, and each reservoir varies greatly in plane and vertical.
SHINE portable X-ray diffraction (soil edition) is designed for clay minerals content identification and equipment research and development of a portable X-ray diffraction, it can be based on different clay minerals content of the crystal structure, quickly identify clay mineral type and the specific percentage of the, even small granular mineral can determine accurately, It is the main method of clay mineral identification with the advantages of simple sample preparation, fast and high measurement accuracy.
