摘要
本文用热力学计算了C还原MgO在不同温度下平衡时Mg的分压，并计算给出生成MgO晶须的热力学条件。根据理论计算结果设计了制备MgO晶须的实验，对制备MgO晶须进行了结构分析和形貌观察，证明了理论分析的正确性。
The equilibrium pressures of vapor Mg from the reductive reaction of carbon and magnesia at different tempera-ture were calculated. The thermodynamics conditions of the preparation of MgO whiskers were given. Using the the-oretical results, the preparation experiment of MgO whiskers was designed. The XRD pattern and SEM micropho-tograph of MgO whiskers had proved the correctness of the theoretical analysis.
