FIELD: inorganic synthesis.
SUBSTANCE: iron-chromium-nickel spinels are prepared by homogenization of original oxides of nickel(II), iron(III), and chromium(III) in presence of 0.5-1.5% of potassium halides as mineralizing agent followed by briquetting and heat treatment of oxides at 800-1000°C.
EFFECT: enabled preparation of spinels at lowered temperatures and in shorter time.
