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.

The present invention improves the strength of the bottom (net) of the jig and makes it more difficult and unlikely for deviation of the mesh to occur. A workpiece is loaded on the net (2) of the heat treat furnace jig (hereinafter, heat treatment furnace jig). In the net (2), a first strand (10), a second strand (20) and a third strand (30) are in contact at a contact point (X1). Near the contact point (X1), the second strand (20) overlaps the first strand (10) from above and the third strand (30) overlaps the first strand (10) from below. As a result, the first strand (10) is held between the second strand (20) and the third strand (30) in the up/down directions.

An apparatus and a method of firing a unit cell for a solid oxide fuel cell performs pre-sintering and main sintering using a single apparatus by adjusting a height of a setter to apply pressure. The pressure prevents warping.

A method of producing a ceramic fired body may includes a step of passing a first accommodating shelf through a firing kiln, the first accommodating shelf including a stack of units of a shelf plate and a frame placed on the shelf plate, one or more ceramic bodies placed on the shelf plate being surrounded by the frame extending in a circumferential direction between the shelf plates; a step of retrieving one or more frames from the first accommodating shelf which has passed through the firing kiln; a step of using the one or more retrieved frames to build a second accommodating shelf for passing through the firing kiln; and a step of rotating the retrieved frame such that a rotational position of the retrieved frame when the second accommodating shelf passes through the firing kiln is different from a rotational position of the retrieved frame when the first accommodating shelf passed through the firing kiln.

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 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.

A workpiece carrier and method for producing a workpiece carrier (10) for providing and handling workpieces in high-temperature ovens for high-temperature treatment or similar, said workpiece carrier being made of a support grid (11) having workpiece holders (12) for positioning workpieces on the workpiece carrier, said support grid being made of support struts (14, 15, 16, 17, 19, 20) forming a grid structure (21), said support struts being made of carbon fiber-reinforced carbon (CFC), said workpiece holders being made of positioning devices (22) of the work-piece carrier arranged on the support struts, said positioning devices being arranged on the support struts such that the workpiece can be arranged on the workpiece holder in a predetermined position, said positioning devices comprising a bearing element (24) made of a ceramic fiber composite material, said positioning device being a support element (23) arranged on a support strut for arranging the bearing element.

An assembly for providing a saggar for use in high temperature applications, may include a rectangular base element and first and second sets of two rectangular wall elements, wherein the rectangular base element includes connectors on two opposite sides for connecting with the two rectangular wall elements of the first set of the rectangular wall elements at the two opposite sides. The two rectangular wall elements of the first set may each include a connector at a first edge for connecting with the rectangular base element at the two opposite sides, and the two rectangular wall elements of the first set each may include two recesses in a second edge opposite to the first edge and in the vicinity of each end of the second edge of the rectangular wall elements of the first set. The two rectangular wall elements may each include two ears for connecting with the recesses.

A heat treatment furnace may include: a furnace body comprising an entrance, an exit, and a heat treatment space having a temperature-rising space and a temperature-maintained space that are configured to thermally treat a plurality of objects; conveying plates on which the plurality of objects is to be placed; a pusher configured to push the conveying plates in a front direction from the entrance to the exit of the furnace body; and a plurality of heaters extending in an up-down direction and aligned in the front direction in the heat treatment space. Each of the plurality of heaters may include a heating part configured to generate heat. Positions of the heating parts of the plurality of heaters in the up-down direction may vary from the heater closest to the entrance toward the heater closest to the exit.

The invention relates to a charge carrier (10) for the defined arrangement of processed objects, the charge carrier comprising, as components, at least a support grid (11) having a plurality of receiving elements for receiving the objects, the receiving elements being connected to the support grid in a form-fitting manner via a plug-in connection, wherein the receiving elements are designed as adapters (25) for the positioned individual reception of the objects, the adapters being received in adapter receptacles of the support grid so as to be arranged in a positioned manner.
