Laboratory of extreme energy effects

This line of research is conducted on a unique experimental setup that allows analyzing the molecular composition of vapor substances at temperatures above 3,300 K. The method of heating by millisecond laser pulses in combination with time-of-flight mass spectrometry is used for the study. Using this method, the evaporation of graphite in the vicinity of its triple point was studied for the first time, as well as the evaporation of a number of super-refractory ceramics at temperatures above 4000 K.

The work is devoted to the experimental study of the high-temperature behavior of a number of super-refractory compounds - carbides, nitrides of metals of groups IV and V. These compounds, due to their thermophysical and mechanical properties, are considered as new structural materials for space and nuclear technology. In our laboratory, the parameters of the phase diagrams of these compounds are determined - solidus and liquidus temperatures, as well as a set of the most important thermophysical characteristics - emissivity, thermal conductivity and heat capacity, coefficient of thermal expansion, etc. To measure these properties, a number of specially designed devices and developed data processing algorithms are used, allowing measurements in the temperature range inaccessible with the use of standard commercial equipment.
