摘要

为了描述机械研磨得到的粉末材料的反应性，提出了一个热力学判据——表面活性。结果表明，由气体俘获法测定的粉末材料比表面值计算的表面活性与气体渗透法测定的系统比表面之间存在函数关系，从而可以得出原料系统机械活化的有效性。

MINERAL POWDERS: ACTIVITY AND SPECIFIC SURFACE AREA

A thermodynamic criterion – surface activity – is proposed in order to describe the reactivity of powder materials obtained by mechanical grinding. It is shown that there is a functional relationship between the surface activity calculated from the specific surface values of powder materials determined by gas trapping method and the specific surface of these systems determined by gas permeability method, which allows us to conclude about the effectiveness of mechanical activation of raw materials systems.
