RATE OF CONTACT FUSION OF ALKALI METAL-HALIDE CRYSTALS

Abstract

The rate of contact fusion of alkali metal-halide crystals NaCl-KI, KI-KCl, and KI-NaBr was related to temperature by the exponential law. The powder salts were pressed into tablets. One tablet was placed in a crucible in a furnace, and the other sample was suspended just above the sample in the crucible. During the heating and at a predetermined temperature, the suspended sample was brought in contact with the lower sample. The rate of contact fusion was recorded on a thermogram. Melts obtained from contact fusion of KI-NaBr crystals at different temperatures had similar compositions.
