FIELD: chemistry.
SUBSTANCE: zirconium hydroxide is precipitated and then simultaneously dried and calcined under microwave radiation in the frequency range 50-20000 MHz with continuous power of 3.0-50.0 kW for 5-60 minutes.
EFFECT: invention reduces aggregation of zirconium dioxide nanopowder and increases specific surface area of the powder.
