Direct current-induced bonding between single- and polycrystalline manganese-zinc ferrites

The application potential of de electric fields to promote and optimize the ferrite bonding between single- and polycrystalline manganese-zinc ferrite was investigated. The ferrite bonding process was accelerated under the ap plication of a de electric field. The degree of bonding increased as the bo nding time and bonding temperature were increased, It was also found that t he direction of an applied current from the poly- to single-crystalline fer rite regions enhances bonding.
