Abstract:

The article is devoted to an estimation of phase transformations of silicates magnesium at heating in the temperatures range from 0 degrees C to 1100 degrees C. The object of study is a silicates of magnesium containing oxide nickel ore. Differentially-thermal (NETZSCH 449 C - Jupiter), weights - spectrometer (QMS 403 C Aeolos), high-temperature X-ray diffraction, electron-probe microanalysis (JSM - 5900 LV) and chemical analysis methods have been used in the study. The temperature ranges of existence Mg(6){[}(OH)(8)Si(4)O(10)] and Mg(2)Si(2)O(6) are obtained. Parameters of an elementary cell of the above minerals and their changes with temperature and features of nickel distribution in magnesium silicates with various ration MgO/SiO(2) are defined in this work.
