白云石一次碳化法制备高纯MgO研究

Research on Synthesis of High-pure MgO by Dolomite Primary Carbonization Method

以河北井陉白云石为原料,进行碳化一次法制备高纯MgO的实验研究,分析了碳化反应过程中液固相中钙镁盐组成和结构的变化规律及反应机理。确定了制备高纯MgO的适宜条件,制得了纯度为99.2%的MgO产品,为我国白云石资源的开发利用提供了一定的理论依据。

To conduct the experimental research on synthesizing the high-pure MgO using the dolomite of Jingxing as the material by the primary carbonization method and analyze change rule and reaction mechanism of the Ca-Mg salt constitution in the fluid-solid phase and construction. To make sure that the suitable condition of synthesizing the high-pure MgO and synthesize 99.2% MgO. To provide a certain theoretical basis for the exploitation and utilization of dolomite resource of China.
