Ferrite synthesis
Soft ferrites for power electronics

Ferrites are synthetic mixed oxides produced at high temperatures from transition metal oxides or carbonates. Their synthesis leads either to polycrystalline materials, which are today's best-selling magnetic ceramics, or to single crystals, which are of far less industrial importance.

• Single-crystal ferrites

  Single-crystal ferrites are synthesized by a variety of methods: hydrothermal synthesis, growth in molten oxide media and pulling synthesis. The latter is used for industrial single crystals. The advantage of single crystals is a very dense material with a very good surface quality (polishing is nevertheless necessary). The disadvantages are more numerous: heterogeneity of chemical composition, limited formats (plate or disk), delicate machining and high cost. Until now, single-crystal ferrites have mainly been...
