Kinetics of Formation and Thermal Stability of Mg_2(OH)_3Cl-4H_2O

摘要

Magnesium oxychloride cement (MOC) is an important material in building industry for its unique properties. In this contribution, we prepared and characterized pure Mg_2(OH)_3Cl.4H_2O. The phase composition and kinetics of formation was evaluated by X-ray diffraction, where diffractograms were observed continuously for 4 hours. The chemical composition was analyzed using X-ray fluorescence and energy dispersive spectroscopy. Also, scanning electron microscopy was used to analyse the microstructure. In addition, thermal stability was tested using simultaneous thermal analysis.
