Abstract
The concept of surface modification of nano-scale particles with short-chained organic molecules has been used for the preparation of deagglomerated slurries of n-TiN using guanidine propionic acid as surface modifier, the strongly agglomerated powder could be redispersed to its primary particle size of 30 to 40 nm. From such suspensions green specimens with densities of 50% could be prepared by pressure filtration, which could be sintered to high densities (>96%) at temperatures below 1400°C without significant grain growth
