    Properties. The alkali metal halides exist as colourless crystalline solids, although as finely ground powders appear white. They melt at high temperature, usually several hundred degrees to colorless liquids. Their high melting point reflects their high lattice energies. An effect of particle size upon the heat capacity of sodium chloride has been found in the temperature range 9° to 21°K. The experiments were done with three NaCl samples of specific surfaces between 38 and 59 sq. meters per gm. The observed effect has the temperature dependence predicted by Cited by:

Sticking occurs only when molten material wets the crucible wall, particularly when both contain the same type of exchangeable ions. In alkali halides, an important role is played by oxide and hydroxide ions and elimination of such impurities thus avoids wetting problems.

In this paper, we present the first systematic study of correlations between energy levels of (Tl +) 2, (In +) 2, and (Ga +) 2 dimer centers and the crystalline environment by using dielectric theory of chemical bonding for complex crystals.

Our model has successfully built links between the E A′, E B′, and E C′ of these centers and the environmental factor by: 3. The surface tensions of methanol, acetone, dimethylformamide, dimethylsulfoxide, and methylamine over limited temperature ranges, and of solutions of alkali halides in the first three of these liquids at 25 °C have been measured by the method of maximum bubble pressure, with precautions against moisture.

However, with the addition of alkali halides, the local environment of Eu ions changes and the interaction between excited 4f electrons and local conduction band (or the charge transfer band) becomes possible. The Eu 3+-ion can acquire an electron and be reduced to the Eu 2+ by: 1. The photoacoustic effect, produced by the F-center in alkali halide crystals, is analyzed using the configuration coordinate : Luis Da Silva.
