Document Type and Number:
WIPO Patent Application WO/2023/182211
Kind Code:
A1
Abstract:
The present invention provides at least one of: a high gallium nitride sintered body in which an increase in oxygen content caused by reoxidation after sintering is suppressed, as compared to a conventional gallium nitride sintered body obtained by a hot press treatment; a production method for the same; and an application of the same. Provided is a gallium nitride sintered body comprising a surface layer that has a higher density than the inside of the sintered body, wherein the atomic weight ratio of gallium with respect to the total of gallium and nitrogen is more than 0.5 but not more than 0.60.
