Abstract
Studying point defects under thermal equilibrium conditions is basically superior to using non-equilibrium measurements. Consequently investigation of thermophysical properties at high temperatures should become the principal method for obtaining data on formation energies and equilibrium concentrations of point defects in solids. The equilibrium vacancy concentrations increase rapidly with the temperature. It is advantageous to employ the modulation methods for determining the vacancy contributions, especially for metals, where it has been found that the equilibrium vacancy concentrations reach values of the order of 1% at the melting points. The vacancy concentrations are especially high in refractory metals. 82 refs.
