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 %: polyacrylic acid 0.2-0.6, isopropyl alcohol 4-10, water 27-43, stoichiometric mixture of barium carbonate and iron oxide - the rest.
EFFECT: increased activity by grinding a mixture of the starting ferrite component in the production of barium hexaferrite, providing the synthesis temperature reduction firing batch products.
