Abstract
A surface treatment method for aluminum nitride includes the steps of: obtaining an aluminum nitride powder; and treating the aluminum nitride powder with a surface modifier by: (a) simultaneously grinding and mixing the aluminum nitride powder with the surface modifier, or (b) grinding the aluminum nitride powder and subsequently mixing the same with the surface modifier.
Claims20
A process for producing water-resistant aluminum nitride powder, comprising:
- obtaining an aluminum nitride powder;
- and
- treating the aluminum nitride powder with a surface modifier by:
- (a) simultaneously grinding and mixing the aluminum nitride powder with the surface modifier, or
- (b) grinding the aluminum nitride powder and subsequently mixing the same with the surface modifier.
A process for producing an aluminum nitride powder via a combustion synthesis which comprises:
- preparing an aluminum container;
- placing a particulate aluminum into said aluminum container;
- and
- heating said aluminum container and said particulate aluminum in a nitrogen atmosphere to proceed with a self-propagating combustion, wherein said aluminum container undergoes a reaction with nitrogen.
