Abstract: | The theory of the pre-melting phenomena in ionic crystals on the basis of the concept of the hetero phase fluctuation has
been applied to KCl and AgCl crystal. The large scale molecular dynamics simulations (MD) in KCl and AgCl crystals are also
performed to examine the ionic configuration in premelting region in the vicinity of their melting points. The size of the
liquid like clusters are estimated by the theory and MD. The structural features of liquid like clusters are discussed by
MD results using the Lindemann instability condition. The ionic conductivities in the pre-melting region are also discussed
on the same theoretical basis. |
