Modification of alumina and carbon particles using silane and methane was carried out in a D.C. plasma‐jet fluidized bed reactor at atmospheric pressure. XRD, SEM and EPMA results showed that b‐SiC was formed inside and on the surface of the carbon particles. For the alumina particles, metallic Si was deposited inside and on the surface of the particles, but unfortunately the X‐ray reflection peak of b‐SiC was difficult to observe due to interference by the alumina peak. Speculations are offered concerning the mechanism of the deposition inside and on the surface of the particles.
