FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing copper (II) ferrite with a tetragonal spinel structure and can be used in chemical industry in sulphuric acid production processes. Initial iron (III) and copper (II) oxides are homogenised with addition of a mineralising agent - potassium chloride in amount of 0.5-1.5 wt % to the mixture of oxides, the mixture is briquetted at pressure 10 MPa and then thermally treated at temperature 850-1000°C.
EFFECT: method enables to obtain copper (II) ferrite with shorter duration of synthesis in a single step, which enables to reduce power consumption, time expenses, labour input into the process and reduce the cost of production.
