Abstract

This paper introduces the use of Viscous Plastic Processing (VPP) for the production of microwave ferrite materials and components. Conventional ceramic processing methods produce bulk ferrite materials restricted to relatively simple shapes and that can possess significant micro-structural defects resulting in poor mechanical properties. Using VPP the microstructures and physical strength of ferrite materials can be substantially enhanced and entirely new and unique device geometries produced, such as those based on ferrite helices. Ferrite Materials produced by VPP, such as lithium based ferrites, will be compared to those produced by standard methods of production such as powder pressing.
