Abstract : The design and operation of a novel forced flow reactor for synthesizing nanocrystalline, high surface area (210 - 250 sq m/g) TiN powders is described. A key in tailoring the characteristics of the powder produced in the reactor is the use of a microwave-generated plasma. Sintering results demonstrate the tremendous potential for pressureless sintering of monodisperse, high surface area nitride powders as well as highlight the need for processing which addresses the proclivity for oxidation of these materials.
