To provide a baking vessel for silicon nitride ceramics, a baking device for ceramics, and a ceramics baking method capable of easily blowing nitrogen gas evenly on a whole without complicated structure or a mechanism even when carrying out baking by plurally housing silicon nitride compacts, particularly honeycomb compacts including metal silicon particles and/or silicon nitride particles in the container in multiple rows, and capable of efficiently carrying out heat treatment such as nitriding and sintering at high quality with favorable form accuracy without deformation, defects or the like.
The baking vessel 1 for ceramics is for housing a plurality of the compacts 15 in multiple rows in vessel bodies 1a, and it is provided with a gas inlet 2 formed on at least one optional wall face of the vessel body 1a, and a gas outlet 3 formed on a wall face of the vessel body 1a apart from the one wall face.
