Filed: 1987-02-19
Abstract: PURPOSE:To produce a single crystal ferrite having required size in high yield, by bring the single crystal ferrite into contact with a ferrite powder having composition as similar as the above-mentioned single crystal ferrite, heat-treating and subjecting the whole to single crystallization. CONSTITUTION:A single crystal ferrite is brought into contact with ferrite powder having composition as same or near as the above-mentioned ferrite and the contact face of the single crystal ferrite with the ferrite powder is subjected to heat treatment in a pressure state. Interface reaction is induced by the heat treatment to join the contacting face together and the whole the ferrite is subjected to single crystallization to provide the aimed ferrite. The single crystal ferrite having reduced segregation can be produced in high yield, short single crystallization time and large scale, in order to subject the ferrite powder to single crystallization after completely joining the interface together. A single crystal having arbitrary shape fit in a capsule by encapsulating the ferrite powder contacted with the single crystal ferrite into the capsule having required shape can be produced.
