Abstract
A method for determining the formation energy of vacancies in phlogopite is proposed, based on an analysis of how elementary defects in its crystal lattice, associated into complexes, influence the temperature dependence of its electric conductivity. The existence of a linear relationship between the melting temperature and vacancy formation energy for the studied phlogopite samples with different impurity contents was shown. The author calculated the dependence of the obtained melting temperatures on the content of the Al, Mg, and F components in phlogopite samples, which, when associated into complexes, activate the formation of elementary lattice defects.
期刊介绍：
High Temperature is an international peer reviewed journal that publishes original papers and reviews written by theoretical and experimental researchers. The journal deals with properties and processes in low-temperature plasma; thermophysical properties of substances including pure materials, mixtures and alloys; the properties in the vicinity of the critical point, equations of state; phase equilibrium; heat and mass transfer phenomena, in particular, by forced and free convections; processes of boiling and condensation, radiation, and complex heat transfer; experimental methods and apparatuses; high-temperature facilities for power engineering applications, etc. The journal reflects the current trends in thermophysical research. It presents the results of present-day experimental and theoretical studies in the processes of complex heat transfer, thermal, gas dynamic processes, and processes of heat and mass transfer, as well as the latest advances in the theoretical description of the properties of high-temperature media.
