Abstract:

Synthesis of nonoxide powders in a nonthermal microwave plasma was demonstrated, using SiC, Si3N4 and Si as model materials. Particle sizes are ultrafine, 2-5nm. Compositions and structures have been characterized. Equipment has been developed and characterized. Creep of polycrystalline AlN has been investigated for the first time. Mechanisms are identified.
