Setter plates are fabricated from Li-stuffed garnet materials having the same, or substantially similar, compositions as a garnet Li-stuffed solid electrolyte. The Li-stuffed garnet setter plates, set forth herein, reduce the evaporation of Li during a sintering treatment step and/or reduce the loss of Li caused by diffusion out of the sintering electrolyte. Li-stuffed garnet setter plates, set forth herein, maintain compositional control over the solid electrolyte during sintering when, upon heating, lithium is prone to diffuse out of the solid electrolyte.

A grid-type workpiece carrier includes parallel strip-type first grid elements having recesses, and strip-type second grid elements arranged transverse to the first grid elements and having recesses, wherein the recesses of the first and second grid elements engage in one another in such a way that the crossing first and second grid elements form a grid, wherein the first grid elements are mechanically securely fixed to second grid elements that are arranged in an edge region on opposing sides of the grid.

To provide a heat treatment member and the like that, even when repeatedly loaded into a heat treating furnace, suppresses the occurrence of deformation, cracking, and the like, allowing use for a prolonged period of time, and enables uniform and sufficient carburizing treatment of a part to be heat-treated. The above-described problem is solved by a heat treatment member constituting a heat treatment structure repeatedly loaded into a heat treating furnace with a part to be heat-treated placed thereon, hooked thereto, or the like, comprising an ST member composed of a steel material or a Ni alloy material and a CC member composed of a carbon composite material being detachably combined. At this time, the ST member is preferably a member fabricated by a lost wax process, and the heat treatment member is preferably a hooking member for hooking the part to be heat-treated, a support member for supporting the hooking member, a mounting member for mounting the part to be heat-treated, or a stacking auxiliary member or a support column member for stacking each of these members.

A shell (10) acts as a transporting shoe for steel ingots, which are pushed through a preferably tubular induction furnace for inductive heating for the purpose of producing seamless tubes by the extrusion process. The shell (10) is formed in such a way that it partially reaches around the contour of the steel ingot to be heated. The shell is provided at one end leading in the pushing-through direction or transporting direction, with a shoulder (12), which extends at an angle to the transporting direction, against which the steel ingot rests in such a way that the pushed-through steel ingot takes the shell (10) along with it. A method for inductively heating steel ingots uses a shell (10) as described.

A multi-part support element for spacing carrier elements, includes an upper part and a lower part, wherein the upper part can be detachably axially connected to the lower part by a rotary connection in order to fix a carrier element between the upper part and the lower part, the rotary connection is formed by a stud provided on the lower part and an opening provided on the upper part, into which the stud can be screwed, and the rotary connection is implemented such that the rotary connection is released again after defined screwing of the stud into the opening, such that the stud is locked in the opening with axial play, and wherein the lower part has a disk-shaped attachment, whose layer thickness decreases toward the edge.

In various embodiments, apparatuses for receiving and supporting one or more components during processing thereof at process temperatures greater than approximately 1000° C. feature refractory metal shelves separated by refractory metal support posts.
