Abstract

TiN sintered bodies and coatings are produced by dispersing nanocrystalline TiN powder in water and/or a polar organic solvent as dispersing agent in the presence of at least one low molecular organic compound having at least one functional group which can react or interact with groups on the surface of the powder particles, removing the dispersing agent and sintering the surface-modified TiN which has been processed into green bodies or coatings before or after the removal of the dispersing agent.
