Abstract: The equation between the melting temperature of the material andits high-dispersity are deduced by means of thermodynamic method. The results are suitable for the particles which are circular or non-cir cular.
These equations describe quantitatively the fact that the melting emperature of material is lowered with the increaes of its dispersity.d The result of calculation for pb is more agreeable to the experimental tata, obtained by Coombes, than the theoretical data obtained by M. Hasegawa et al.
