The most significant results
The heat capacities of LnPO4, LnVO4, Ln2Zr2O7, Ln (PO4) (1-x) (VO4) x (Ln = REE) - promising multifunctional materials have been experimentally determined. The obtained reliable values of thermodynamic functions are recommended for databases.
The influence of the size of crystals on the heat capacity of nanocrystalline lanthanide orthophosphates of the cerium subgroup of cerium in various temperature ranges is established.
The thermodynamic properties of a number of complex compounds were studied, and the parameters of their thermolysis needed to obtain nanoscale coatings were studied.
Together with the Institute of Physics and Technology, Ural Branch of the Russian Academy of Sciences, TSZP LLC, 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 are investigated.
