THE CLAPEYRON EFFECT IN SUCCINONITRILE - APPLICATIONS TO CRYSTAL-GROWTH

This paper describes experiments that measure the Clapeyron effect, i. e., the change in melting temperature with static pressure in succinon itrile (SCN), a common model material used in crystal growth experimen ts. The Clapeyron results also yield information about the density cha nge upon solidification - a parameter that is difficult to measure acc urately and directly in SCN due to void formation in the solid. Furthe rmore, making a pressure change in an experimental environment present s researchers with a way to change more rapidly and uniformly the supe rcooling of a melt than by using conventional heating and cooling tech niques.
