The purpose of this investigation is to discriminate the differences in the physical proprties of magnesium hydroxides obtained by the different preparing processes, using the Debye-Scherrer's method of X-ray. The methods used for the preparations of magnesium hydroxides are as follows:-the reactions of magnesium salts and alkalies, the reactions of water and magnesium oxide which is made by calcining magnesite or by burning metallic magnesium. As a result of this investigation we cannot find any difference in the diffraction rings appeared on the films, excepting distribution of the intensity. The distances of planes oftained by Bragg's equation () and their indices determined by Hull-diagram for hexagonal system are as follows: we think that the difference of distribution of the intensity deponds upon the form and size of the crystal particles. the Axial ratio of these magnesium hydroxides was similartto that of natural Brucite, too.
