Compositions from the ternary system BaO-B2O3-Fe2O3 are useful for the synthesis of modified single crystalline barium hexaferrite powders by the glass crystallization technique (GCT)[1]. Such special barium hexaferrite powder BaAIIxBIVxFe12-2xO19 (AII: Co2+, Mn2+ e.g.; BIV: Ti4+, Ru4+ e.g.) are a very important magnetic material for different applications. Their technical applications range from high-density magnetic recording media[2], hyperthermia in the medicine[3] to chemical[4] and microwave absorbing materials[5]. Very homogeneous melts (thermal and chemical) and a defined redox ratio are required amongst other things for the manufacturing of such barium hexaferrite powder by GCT. - The melts from the system BaO-B2O3-Fe2O3 are in black. In black melts the heat transport by radiation is nearly zero. Consequently the problems of homogeneity increase. Moreover, the iron irons and the partially substituted AII-ions are paramagnetic ones with a defined magnet moment n*?B. It is very interesting to answer the question, how a low AC magnetic field (<< 1 T) which is impressed during the melting until the cooling can help to homogenize the melt and to adjust the redox ratio and therefore the crystallization - without mechanical contact, controlled and independent on other process parameters. - The influence of high static magnetic (>> 1 T) fields on the crystal orientation and phase transformation in solidified structures of metals, alloys and ceramics of different magnetic permeabilities was recently researched in many cases[7-9]. - In this study a low inhomogeneous AC magnetic field (up to 55 mT, 50 Hz) was imposed in the melts. They contain 33.84 wt% iron oxide. The used experimental set-up as well as the experimental procedure will be described in detail (Section 2). In Section 3 we illustrate and discuss the results by means of in-situ measured temperature distributions using a protected thermocouple an ex-situ (drilled out samples of the cooled melt) by density as well as by X-ray diffraction and vibrating sample magnetometer measurements.
