Title:
ALUMINUM NITRIDE SINTERED BODY AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2017/033855
Kind Code:
A1
Abstract:
This aluminum nitride sintered body has one main surface and contains a plurality of aluminum nitride crystal grains. With respect to the aluminum nitride crystal grains, the (11-20) planes of all the aluminum nitride crystal grains, or alternatively, the (11-20) planes of some aluminum nitride crystal grains and the (10-10) planes of the other aluminum nitride crystal grains are oriented to be parallel to the main surface. Consequently, an aluminum nitride sintered body having a main surface that is easy to be mirror finished and a method for producing this aluminum nitride sintered body are provided.
