Abstract:
Object To investigate the properties of layer crystal structure and its interlayer absorption and expansibility in montmorillonits clay lattice, which provide a basis for the montmorillonite as medicine adjuvant.Methods Montmorillonite sample was separated and purified from clay minerals, and the diameter of particle was less than 1 ?m in colloid, the setting film sample was ready-made, and the samples were analyzed with X-ray diffraction.Results The information of interlayer change pattern on montmori-llonite clay was obtained with different conditions.Conclusion Montmorillonite as swelling and adsorption clay minerals and form an interlayer absorption is possible and the X-ray diffraction can determine the amounts of layer distance.
