Structure and Thermal Transformations of Hydrated Magnesium Silicates

摘要

The article is devoted to an estimation of phase transformations of silicates magnesium at heating in the temperatures range from 0℃ to 1100℃. 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)_8Si_4O_(10)
