Beschreibung
Modern Ferrite Technology, 2nd Ed. offers the readers an expert overview of the latest ferrite advances as well as their applications in electronic components. This volume develops the interplay among material properties, component specification and device requirements using ferrites. Throughout, emphasis is placed on practical technological concerns as opposed to mathematical and physical aspects of the subject.
The book traces the origin of the magnetic effect in ferrites from the level of the simplest particle and then increases the scope to include larger hierarchies. From the desired magnetic properties, the author deduces the physical and chemical material parameters, taking into consideration major chemistry, impurity levels, ceramic microstructures and grain boundary effects. He then discusses the processing conditions and associated conditions required for implementation. In addition to conventional ceramic techniques, he describes non-conventional methods such as co-precipitation, co-spray roasting and single crystal growth.
Electronic materials research scientists and technicians, ferrite manufacturing and research engineers, electronic materials professors and students, electronic engineers in magnetic component design and high frequency power supply engineers will find this book to be an invaluable resource.
Since the publication of the first edition (1990), there have been many significant changes in both ferrite materials and applications. In the materials field, there have been numerous reports of nanoferrites, that is, use of nanocrystalline technologies for producing ferrite particles in the nanometer size range. The properties are vastly different than previous ferrites. To satisfy the ever-increasing frequency of SMPS (Switched-mode power supplies), ferrite power materials have been introduced to operate up to 3MHz. New materials for automotive applications must operate over wide temperature extremes. Materials for hybrid auto power supplies present another new application. Still another ferrite market that has increased recently is ferrites for SDL and other new telecommunications applications. Many changes in ferrite suppliers have also taken place with companies such as Siemens, Philips and Thomson. Globally, China has replaced Japan as the largest ferrite supplier.
