|Title:||Lattice energy of mixed alkali halide crystals:Evaluation from sound velocity studies|
Murthy, N Manohara
|Abstract:||Based on single-crystal elastic constant data and employing Kudriavtsev's theory, which relates the lattice energy of the crystal U to the mean sound velocity μm in the crystal, the lattice energies or NaCl-KCl, NaBr-KBr, Kl -KBr and KCl-RbCl mixed crystals have been evaluated. In general, the lattice energies of these mixed crystal have been found to decrease with increase in the concentration of the second component. The present study highlights the application of Kudriavtsev's theory in predicting the lattice energies of mixed ionic crystals making use of sound velocity measurements.|
