A container for storing a powder mixture during heat treatment in a furnace, a furnace and a method for heat treatment of a powder mixture. The aim of the invention is to specify a container by means of which in particular the throughput per unit of time can be increased and an automatic removal of the container is simplified. This aim is achieved by a plurality of receptacles for releasable fastening of spacers which in the installed state allow contactless stacking of a plurality of containers one above the other.

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.

Disclosed are a sagger for sintering lithium composite transition metal oxide and a preparation method thereof. The sagger includes a substrate layer and a shallow layer on a surface of the substrate layer, and a coating layer. The substrate layer is prepared from the following raw materials: silicon carbide, magnesia-alumina spinel, aluminum oxide-magnesium oxide-yttrium oxide composite fiber, zircon powder and a binding agent; the shallow layer is prepared from the following raw materials: silicon carbide, magnesia-alumina spinel, aluminum oxide-titanium oxide composite fiber, yttrium oxide-zirconium oxide composite fiber and a binding agent; and the coating layer is prepared from the following raw materials: silicon carbide, magnesia-alumina spinel, magnesium oxide, zirconium oxide fiber, lithium composite transition metal oxide powder and a binding agent. The sagger of the present disclosure has properties of good corrosion resistance and a small coefficient of thermal expansion.

A sagger for firing an object to be fired includes an active material for a secondary battery. Carbon dioxide that is a reaction by-product produced during a positive electrode active material firing process can be smoothly discharged from the sagger, and such a smooth discharge of carbon dioxide can lower a residual lithium concentration of a positive electrode active material and thus can improve dispersibility of a positive electrode active material slurry and also improve capacity of a battery.

A method of manufacturing a furnace setter is disclosed. The method includes placing one or more layers of ceramic tape on a form that has a shape corresponding to a desired shape of the furnace setter. The method further includes applying pressure to the assembly that includes the form and the tape layers. The application of pressure to the assembly compresses the ceramic tape layers together to generate an integrated body having the desired shape of the furnace setter. The method further includes removing the integrated body from the form and applying a heat treatment to the integrated body to generate the furnace setter as a sintered solid body. According to a further embodiment, a furnace setter is disclosed that has a weight to area ratio that is less than 10 g/in.sup.2, less than 5 g/in.sup.2, less than 3 g/in.sup.2, or less than 2 g/in.sup.2.

The present invention relates to an apparatus and a method of firing a unit cell for a solid oxide fuel cell, and more particularly, to an apparatus and a method of firing a unit cell for a solid oxide fuel cell, which are capable of performing pre-sintering and main sintering using a single apparatus by adjusting a height of a setter.

A loading tooling for thermochemical treatment of parts includes at least first and second loading stages stacked one on the other in separable manner, each loading stage including a rack extending in a horizontal plane. The rack is supported by four legs extending in a vertical direction with the legs of the second loading stage standing on the legs of the first loading stage. The rack has a plurality of support arms secured thereto, with the plurality of support arms of the first loading stage presenting an arrangement that is different from the arrangement of the plurality of support arms of the second loading stage.

A heat treatment furnace jig having a box-like frame including a rim part and a bottom part, the bottom part being removable from the rim part, and a removable net of woven strands disposed in the box-like frame and supported from below by the bottom part. The net has a triaxial weave of strands, each strand having a bundle of carbon fibers that are aligned without twisting, wherein, among the woven strands, strands of at least one direction are held by two strands in another direction, and the net is impregnated with a matrix material.

The present invention provides a method and apparatus for firing a ceramic component e.g. a ceramic core, within a firing receptacle containing firing powder. The method comprises using a shaping element to shape and/or define an upper surface of a first portion of firing powder at a predetermined height within the firing receptacle. The ceramic component is subsequently placed on the upper surface of the first portion of firing powder e.g. within a depression formed using the shaping element and covered with a second portion of firing powder. The shaping element may comprise a gridded/meshed plate.
