FIELD: chemistry.
SUBSTANCE: wet grinding of 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, isopropyl alcohol 4.0-10.0, oleic acid 0.1-0.5, water 28-45, stoichiometric mixture of strontium carbonate and iron oxide - the rest.
EFFECT: increasing the activity when the mixture of initial ferrite-forming components is ground, which reduces the synthesis temperature and increases the coercive force from the magnetization of strontium hexaferrite.
