SINTERING OF REFRACTORY COMPOUND NANOCRYSTALLINE POWDERS. I. STORAGE AND PRELIMINARY HEAT TREATMENT OF TITANIUM NITRIDE NANOCRYSTALLINE POWDERS

摘要

Several approaches are considered for storing and processing finely-dispersed oxygen-free refractory compound powders using the example of titanium nitride nanopowder. The change in composition of nanopowders protected by a surfactant and without protection from oxidation during storage in air, and also during processing in gas atmospheres (nitrogen, hydrogen) and in a vacuum is studied.
