To provide a baking container for silicon nitride-based ceramic in which a silicon nitride-based molded article, especially, a honeycomb molded article containing metal silicon particles and/or silicon nitride particles can be subjected to thermal treatment such as nitrization and burning without any deformation and defect, with accuracy in shape, high quality and high efficiency.
The baking container for silicon nitride-based ceramic is a sealed container 20 having a gas introduction port 1 and a gas discharge port 9, the inside of the sealed container 20 is partitioned into a gas introduction chamber 2 in communication with the gas introduction port 1 and a baking chamber 3 in communication with the gas discharge port 9 and accommodating an article 7 to be thermal treated by a gas introduction chamber partition wall 4, and a air-through hole 5 is selectively formed near an outer peripheral part of the gas introduction chamber partition wall 4.
