FIELD: chemistry.
SUBSTANCE: wet grinding of a stoichiometric mixture of barium carbonate and iron oxide is carried out in an acidic medium containing polyacrylic acid and isopropanol at the following ratio, wt %: 0.2-1.8 of citric acid, 2-8 of isopropyl alcohol, 28-32 of water, stoichiometric mixture of barium carbonate and iron oxide - the rest. As a result, the synthesis activity of the original ferrite components significantly increases, thereby reducing the of barium hexaferrite synthesis temperature and products sintering temperature.
EFFECT: increased coercive force in terms of barium hexaferrite magnetization.
