  • Fabrication of ferrite material
    Patent number: 4247500
    Abstract: A method of fabricating ferrite material which results in high permeability and/or fast thruputs. Binder systems are employed such that the components burn out completely and sequentially during sintering and result in the proper grain size and surface properties for high permeability in the ferrite material. In particular, the binder system comprises polyvinyl alcohol, polyvinyl pyrrolidone and methyl cellulose.
