Abstract : The general object of this invention is to provide a method of making ferrite elements for use in millimeter-wave ferrite control devices. A more particular object of the invention is to provide such a method of making ferrite elements in volume numbers at lower costs eliminating the slower molding processes that requires additional processing steps. It has now been found that the aforementioned objects can be attained by arc-plasma-spraying the ferrite materials into a mold type cavity having the configuration of the desired ferrite element or into an array of identical mold type cavities or impressions, each cavity having the configuration of the desired ferrite element.
