An article including an inorganic compound according to the present invention includes a porous part and a no-porous frame body surrounding the porous part in a plane direction, and includes a stress relaxation part between the porous part and the frame body.

The present invention relates to a saggar for firing an active material of a secondary battery, a method for manufacturing the saggar, and a method for firing the active material. The saggar for firing an active material of a secondary battery according to the present invention has a coating layer formed on a bottom surface or a wall surface thereof so as to collect carbon dioxide. By means of the coating layer, the concentration of the carbon dioxide in the saggar can be lowered by collecting the carbon dioxide that is a by-product resulting from a firing reaction, thereby enabling a reduction in the amount of remaining lithium in the active material. The saggar of the present invention provides the saggar for firing an active material of a secondary battery, wherein the saggar has at least one through hole in the bottom surface, or the bottom surface and wall surfaces thereof so as to communicate a gas.

The invention relates to a method for producing a component from ceramic materials in which a plurality of layers are applied to a base body by means of screen printing or template printing, said layers being formed from a ceramic material, in each case in a defined geometry above one another in the form of a paste or suspension in which powdery ceramic material and at least one binder are included. At least one region is formed here within at least one layer having a defined thickness and geometry composed of a further material that can be removed in a thermal treatment and that is likewise applied in the form of a paste or suspension by means of screen printing or template printing. Electrically functional structures composed of an electrically conductive or semiconductive material are applied to and/or formed on and/or in at least of the ceramic layers prior to the application of a further ceramic layer. The layer structure is then sintered in a thermal heat treatment, with the further material being removed and at least one hollow space being formed with defined dimensions of width, length, and height.
