Rochelle salt owes its importance to the fact that it possesses piezo-electric properties which are much greater in magnitude than in the case of any other known Substance. Nicholson points out that whereas the larger of the two piezo-electric moduli of quartz is 0.0677 E. S. U. per kilogram, a usual value for Rochelle salt is 10 E. S. U., and this can be increased to 200 E. S. U. per kilogram for crystals grown in a special manner so as to develop what is known as a composite structure.

We performed MD-simulation of two dimensional elastic disks in a microcanonical ensemble and observed the pressure versus the density for the different elastic moduli. As was found in Alder’s simulation, we reconfirmed a plateau in the (pred, ρ*) diagram as an indication for a phase transition with better statistics and observed its dependence on the elastic modulus. This dependence can be explained by the effective density reduction due to the elasticity of the disks. This suggests the universality of the Alder transition of the hard core potential for the contacting elastic potentials. A discussion of a geometrical order parameter |ɸ|2 is included.
