FIELD: metallurgy.
SUBSTANCE: invention can be used in chemical industry. The method of obtaining of copper ferrite (II) includes the addition of sodium nitrite to hot solution of salts of iron (II) and copper (II). Sodium hydroxide solution is added to the obtained mix. The evolved mix of oxides of iron (III) and copper (II) is separated from solution, washed out by distilled water and dried up to the constant mass then it is heat treated.
EFFECT: invention allows to obtain copper ferrite (II) using iron salts (II) and to accelerate ferritisation process.
