本研究通过数学模型对MgO的机械化学合成条件进行了预测，并进行了相应的实验验证。球磨过程是一种易于在工业过程中实施的过程，但涉及多个参数，这使得确定最佳操作条件变得非常复杂。已确定，无论研磨材料或使用的条件如何，MgO 的反应区的累积能量都在 41 至 64MJ/mol 之间。在该区域之上，仅获得 MgO。必须具有 24 至 48 Wh/g 之间的能量并且具有大于 0.025 J/hit 的冲击能量才能触发 MgO 的机械化学合成。
This study deals with the prediction, by a mathematical model, and the corresponding experimental confirmation of the mechanochemical synthesis conditions ofMgO. The ballmilling process is a easy to implement in industry process but that involves several parameters whichmake it very complex to identify the optimum operating conditions. It was established that the reaction zone ofMgO is between accumulative energies of 41 to 64MJ/mol regardless of the grinding material or the conditions used.Above this region only MgO is obtained. It is necessary to have energies between 24 and 48 Wh/g and to have energies of impact greater than 0.025 J/hit to trigger the mechanochemical synthesis of MgO.
