AbstractBased on the reuse of by-products in the silicone industry, a simple catalyst-free method has been developed for the synthesis of SiC powders in a thermal plasma system. Detailed structures of the as-prepared products were characterized. Crystals collected showed two types of morphologies, which were spheres and crystals with specific exposed facets. The spherical nanoparticles were attributed to high cooling rate of droplets. The latter ones can formed according to their crystal growth habits. As a result, the equilibrium forms of beta-SiC were found to be polyhedra with regular or irregular shapes, while for alpha-SiC were mainly nano-platelets with (001) faces on the upper and basal planes and a few polyhedra based on platelets. By improving diffusion of reactants, the contaminations of products can be significantly reduced. (C) 2013 Elsevier B.V.
