Pokraskin This process was developed by Toshiba [5.36]. The starting materials for barium ferrite production are dissolved in a borate glass melt. The molten material at ca.
1200 °C is quenched by pouring it onto rotating cold copper wheels to produce glass flakes. The flakes are then annealed to crystallize the ferrite in the glass matrix. In the final stage the glass matrix is dissolved in acid. In a variation of this process, the glass matrix is produced by spray drying [5.37].
