The Thermodynamics of Crystallization Pressure

  • V. Ya. Khaimov-Mal’kov

Abstract

It has often [1–14] been observed that crystals growing in a medium containing foreign particles repel the particles as well as trap them. Our photographs (Figs. 1, 2, and 3) show such repulsion. Lavalle [4] was the first to notice the effect in 1853, There is as yet no agreement in explanation for the effects, nor is there any agreement In data on the pressures that may occur. Somegive values of 10 kg/cm2 or so [3–5, 10], others only a few g/cm2 [6, 7, 12, 14]. The latter value has been adopted in monographs on crystal growth [13, 15]. These discrepancies have, of course, meant that fundamentally different explanations can be given for the effect. Those who take the pressures to be small explain the effect as a surface interaction (between crystal, melt, and particle). Those who take the pressures to be large relate the repulsion to the energy of the phase change.
