Study on Preparation of Mg(OH)2 as New Flame-Resisting Materials from Dolomite through the Carbonization
Abstract:
The optimal conditions of prepared magnesium hydroxide using dolomite as raw material were systematically explored by carbonization. The influence between the factors of reactions and the extraction rate of magnesium hydroxide was studied. The structure and composition of product were analyzed by Fourier transform infrared spectrometer, X ray diffraction and electron microscopy. In the conditions, the extraction rate could be up to 90.32%, and its crystal was a hexagonal-type. This method has many kinds of advantages, such as simple operation, low costs of production, eliminating the environmental pollution and comprehensive utilization of by-products.
