FIELD: chemistry.
SUBSTANCE: wet grinding a stoichiometric mixture of strontium carbonate and iron oxide in a medium containing polyacrylic acid, triethanolamine, isopropyl alcohol and oleic acid, with the following component ratio, wt %: polyacrylic acid 0.2-0.6, triethanolamine 0.2-0.6, isopropyl alcohol 2.0-5.0, oleic acid 0.1-0.5, water 28-45, stoichiometric mixture of strontium carbonate and iron oxide - the rest.
EFFECT: increasing the coercive force of strontium hexaferrite magnetization, and increasing the activity during grinding a raw ferrite components mixture in the strontium hexaferrite production.
