The Effect of Microstracture inMagnetic Properties of Barium Ferrite
To study the effect of microstracturcs,long-time grinding and nonmagnetic phase on magnl;tic properties of barium fe rrite, isotropic samples of ba rium ferrile magnets, BaU.6Fc203. were prepared by ce ra mics and co - precipitation methods. Magnetic measurments indi ca tes a higher demagnetization of the samples prepared by <.:hemical method due to lack of rcmcnant stress and crystallographic imperfect ions in th is case. Also, the inter med iate nonmagnetic phases is less in samples prepared hy chemical method. The optimum si ntering temperature for maximum store of magnet ic e nergy is 925-950°C fo r che mica l and 950- 1000°C for ceramic methods.
