FIELD: methods of production of spinels in chemical industry for production of catalysts.
SUBSTANCE: proposed method of production of nickel ferrite-chromite (II) having structure of spinel includes homogenization of initial material mixture containing nickel (II) oxide, chromium (IV) oxide and dihydrate ferrous oxalate (II). Mixture thus obtained is briquetted and is subjected to heat treatment at temperature of 800-1000°C.
EFFECT: reduction of temperature and duration of process.
