FIELD: chemistry.
SUBSTANCE: invention can be used in making thermochromic material, cathode material for lithium current sources, thermistors, thermal relays, switching elements. To obtain vanadium dioxide nanoparticles of monoclinic crystal system, method includes hydrothermal treatment of a mixture of ammonium metavanadate NH4VO3 and an organic acid and subsequent annealing of obtained product in a vacuum or inert atmosphere. Organic acid used is citric acid. Hydrothermal treatment is carried out at pH 4.0-5.5 and temperature of 180-220 °C for 2-20 minutes. Annealing of product is performed at temperature 350-370 °C for 5-60 minutes.
EFFECT: invention enables to lower temperature and duration in production of vanadium dioxide of monoclinic crystal system, obtain particles with morphology of corrugated nanoplates.
