Abstract

Ferrite bodies are commonly fabricated by compressing powdered oxides into desired shapes and then sintering the compressed bodies to obtain the desired magnetic properties. In the fabrication of certain complex structures, such as the one shown at the right, it is difficult to create the desired shape by a single compressing operation.

Method of Forming Complex Ferrite Bodies

Ferrite bodies are commonly fabricated by compressing powdered oxides into desired shapes and then sintering the compressed bodies to obtain the desired magnetic properties. In the fabrication of certain complex structures, such as the one shown at the right, it is difficult to create the desired shape by a single compressing operation.

This difficulty is overcome by forming the complex structure in a plurality of simple component parts in the conventional manner, then assembling the parts and unifying them by solid state reactions which occur during the sintering cycle. Bonding is effected by crystallite formation eliminating the interfaces between components. It may be encouraged, if necessary, by application of pressure to the assembled parts during the sintering operation.
