Abstract: A transport tray for transporting and heating chemical substances, includes a one-piece support structure with a base and a frame fixedly connected thereto, wherein the support structure supports a lining of a tray-shaped cavity for accommodating the chemical substances, wherein the lining includes a base plate lying on the base and multiple frame plates clamped against the frame, wherein the lining is supported by the support structure such that the thermal expansions of the base plate and the frame plates in their plate planes are not impeded.

Abstract: A sagger receiving element for burning powdery cathode materials for producing lithium ion accumulators including a rectangular shell comprising four side walls and a base, wherein the sagger receiving element is produced by a burning process from heat-resistant material which withstands temperatures of in particular more than 900° C., and wherein the material of the sagger receiving element is produced on the basis of oxide-bonded SiC, the material having the following chemical composition in percent by weight to a total of 100%: silicon carbide (SiC) content in a range of 40.0%-80.0%, Al2O3 content in a range of 10%-43%, total SiO2 content in a range of 5%-30%, and alkali oxide and iron oxide content of less than 2%.

Abstract: 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.

Abstract: A transport trough, in particular for a continuous furnace for transporting and heating of chemical substances, includes a flat bottom, and a circumferential frame which, together with the bottom, forms a trough-shaped cavity for holding the chemical substances, wherein the frame is connected to the bottom in a non-destructively detachable manner.
