FIELD: chemistry.
SUBSTANCE: present invention relates to obtaining sodium ferrate (VI), which can be used as an oxidising agent. The method of obtaining sodium ferrate (VI) involves reaction of sodium peroxide with iron (III) oxide in the presence carbon, which is used as the fuel material, taken in amount of 1.5-2.5 % of the mass of the reacting components. To prepare the initial working mixture, iron (III) oxide and carbon are mixed and sodium peroxide is then added to the obtained mixture. Reaction of iron (III) oxide, sodium peroxide and carbon is initiated by local heating of the mixture to temperature of about 500°C.
EFFECT: product with high content of sodium ferrate (VI).
