Texture and microstructural development in gelcast barium hexaferrite

The development of texture in barium hexaferrite by templated grain growth was studied as a function of the Fe₂O₃/BaCO₃ ratio, B₂O₃ additions in the starting materials, and sintering temperature. A magnetic field was used to orient the template particles during the gelcasting process. Excess BaCO₃ resulted in abnormal grain growth and maximized texture, while B₂O₃ additions promoted coarsening, but no abnormal grain growth.
