Abstract

PURPOSE: To introduce modifying metal into ferromagnetic iron oxide powders without damaging their needle properties, by dispersing ferromafnetic iron oxide powders in an aq. alcohol soln. of modifying metal salt and heating it, when modifying metal being introduced into ferromagnetic iron oxide powders to improve their magnetic properties.
