Abstract
One embodiment of the present invention relates to a method of manufacturing a green sheet, a method of manufacturing a silicon nitride sintered body, or a green sheet molding material. The method of manufacturing the green sheet includes a step of obtaining a silicon nitride water slurry that contains at least silicon nitride, water, and a binder and whose water blending amount is 10 to 70 parts by mass per 100 parts by mass of silicon nitride, a decompression treatment step of decompressing the silicon nitride water slurry to obtain a slurry for green sheet molding, and a sheet molding step of molding the slurry for green sheet molding to obtain a sheet molded body.

A method of manufacturing a green sheet comprising:
- a step of obtaining a silicon nitride water slurry that comprises at least silicon nitride, water, and a binder and whose water blending amount is 10 to 70 parts by mass per 100 parts by mass of silicon nitride,
- a decompression treatment step of decompressing the silicon nitride water slurry to obtain a slurry for green sheet molding, and
- a sheet molding step of molding the slurry for green sheet molding to obtain a sheet molded body.
A green sheet molding material obtained from a silicon nitride water slurry that comprises at least silicon nitride, water, and a binder and whose water blending amount is 10 to 70 parts by mass per 100 parts by mass of silicon nitride.
