The Effect of Particle Size on the Heat of Fusion of Pure Metals

In this paper, the equation between the heat of fusion of the pure metals and its particle size are deduced by means of the thermodynamic method. The size effect on the heat of fusion is formulated. The equation has been proved by a series of calculatioas from the thermodynamic data of some metals. The heat of fusion of metal powder of the high dispersity is smaller than that of non-dispersity.
