通过机械力促使固体物质的晶体结构及物理化学性质发生改变的方法称之为机械活化。为了研究机械活化对氧化锌和氧化铁开始还原温度的影响，对碳热还原反应进行了热力学分析。依据对反应吉布斯自由能参数的对比计算得出，具有机械储能的碳不仅会使氧化铁和氧化锌的开始还原温度显著降低，还进一步改善了碳粉的还原能力，达到了节能降耗的要求。氧化锌的开始还原温度降低了185℃，赤铁矿的开始还原温度降低了105℃。温度降低的主要原因从热力学角度分析是碳在机械活化过程中产生了晶格畸变能和表面能，其中又以晶格畸变引起的位错能和无定型化能为主要储能来源。

Through mechanical urged the solid material crystal structure and physical and chemical properties change method called mechanical activation. In order to study the mechanical activation of zinc oxide and iron oxide reduction temperature, the influence of the carbon thermal reduction reaction thermodynamics calculation and analysis. Based on comparison of reaction Gibbs free energy parameters calculation, the results show that the mechanical energy storage of carbon will not only make the beginning of ferric oxide and zinc oxide reduction temperature decreased significantly, and improve the ability of powdered carbon reduction, has reached the requirement of saving energy and reducing consumption. The beginning of the zinc oxide reduction temperature reduced about 185 ℃, the beginning of the hematite reduction temperature decreased around 105 ℃.Temperature decrease from the perspective of thermodynamics analysis is the main reasons for carbon produced in the process of mechanical activation lattice distortion energy and surface energy, which can to lattice distortion caused by the dislocation and no standard for the major source of energy storage.
