ABSTRACT:
A process for producing an ultrafine silicon carbide powder by passing a granulated blend of silica powder, carbon powder and a carbonaceous binder downwardly through a vertical indirect heating reactor, wherein means are provided for increasing the bulk density of the carbon powder for preventing the disintegration of the blend during the reaction which might result from the use of ultrafine powder as the carbon powder in the blend.
