Konstantin S. Gavrichev

Head of Laboratory, Dr. of Sciences (Chemistry)

  • Synthesis of crystalline and nanoscale substances.
  • Measurement of heat capacity and change in enthalpy of inorganic substances and materials using the methods of adiabatic, relaxation, differential scanning, and drop calorimetry.
  • Study into parameters and nature of phase transformations in matter.
  • Research into thermal decomposition processes of substances by STA and DSC, identification of the relationship between the parameters of transformations and composition of substances.
  • Study into the size factor influence on the thermal and thermodynamic properties of substances.
  • Simulation of temperature dependences of heat capacity.
  • Creation and improvement of precision calorimetric installations; development and improvement of methods to measure thermal and thermodynamic properties.

The heat capacities of promising multifunctional materials LnPO4, LnVO4, Ln2Zr2O7, Ln(PO4)1–x(VO4)x (Ln = REE) were experimentally determined. The obtained reliable values ​​of thermodynamic functions were recommended for databases.

The crystal size effect on the heat capacity of nanocrystalline orthophosphates of cerium subgroup lanthanides in various temperature ranges was identified.

The thermodynamic properties of a number of complex compounds were investigated, and the parameters of their thermolysis required to obtain nanoscale coatings were studied.

In collaboration with the Institute of Physics and Technology, Ural Branch RAS, thermodynamic modeling and deposition of Ta and TaC films and coatings on various materials were carried out.

The thermodynamic properties of a number of minerals were studied.
