Upon producing a transparent polycrystalline material, a suspension liquid (or slurry 1) is prepared, the suspension liquid being made by dispersing a raw-material powder in a solution, the raw-material powder including optically anisotropic single-crystalline particles to which a rare-earth element is added. A formed body is obtained from the suspension liquid by means of carrying out slip casting in a space with a magnetic field applied. On this occasion, while doing a temperature control so that the single-crystalline particles demonstrate predetermined magnetic anisotropy, one of static magnetic fields and rotary magnetic fields is selected in compliance with a direction of an axis of easy magnetization in the single-crystalline particles, and is then applied to them. A transparent polycrystalline material is obtained by sintering the formed body, the transparent polycrystalline material having a polycrystalline structure whose crystal orientation is controlled.

One aspect relates to a method for producing an electrical bushing for an implantable device, a corresponding electrical bushing, and a corresponding implantable device. The method according to one embodiment is characterized in that a green blank is produced and sintered from an electrically insulating base body green blank made of a ceramic slurry or powder and at least one electrically conductive bushing body green blank made of a cermet material. The at least one bushing body green blank is inserted into a bushing opening of the base body green blank to form a composite green blank, a shape of the at least one bushing body green blank and a shape of the at least one bushing opening are complementary to each other at least in sections thereof and prevent slippage of the bushing body green blank through the bushing opening. The composite green blank is sintered while applying a force that keeps the bodies together.
