Density of Crystalline Alkali Chlorides and Their Eutectic Mixtures Near the Melting Point

摘要

The density of crystalline alkali chlorides and their eutectic mixtures near their melting point was first measured with the modified Archimedes's method. The premelting effect found was ascribed to the peculiarities of defects in the crystal lattice before melting. The molar volume and concentration of cooperative defects were calculated with the experimental data obtained.
