The present investigation reports the detailed analysis of the influence of B2O3-doping on magnetic and structural properties of hexagonal barium ferrites (BaFe12O19) synthesized via conventional ceramic technique. The results show that crystalline structure of barium ferrite is improved with small amounts of B2O3 between 0.1 and 1.0 wt%. Single phase particles has been obtained by 1.0 wt% B2O3-doping with calcination at temperatures as low as 850 °C and a range of boron concentration and calcination temperature has been extended in order to find the best synthesis conditions. Optimal properties have been achieved by 0.2 wt% of B2O3-doping and calcination at 1000 °C. The remanence and the saturation magnetizations increase considerably by about 40% in magnitude with B2O3. © 2011 Elsevier B.V. All rights reserved.
