ABSTRACT:
A method of forming a 360.degree. ceramic permanent magnet by utilizing a hot isostatic pressing technique on a ceramic preform paterial cylindrically formed and placed inside a deformable metal housing having an inner diameter that is approximately the same but only slightly larger than the outer diameter of the preform. A solid steel mandrel is provided in the center diameter of the hollow cylindrical preform. Crystal alignment and densification of the ceramic material is achieved by using the hot isostatic pressing technique applied to the outside of the housing, preform and mandrel assembly.
