Method for producing refractory nitrides

Patent ·
OSTI ID:6717727
Disclosed is a process for making fine, uniform metal nitride powders that can be hot pressed or sintered. A metal salt is placed in a solvent with Melamine and warmed until a metal-Melamine compound forms. The solution is cooled and the metal-Melamine precipitate is calcined at a temperature below 700/sup 0/C to form the metal nitrides and to avoid formation of the metal oxide.
