Abstract
A process for obtaining granules for manufacturing a silicon carbide based sintered product, includes a) mixing a powder of silicon carbide SiC particles, whose average diameter dis at least about 2 micrometers with a powder of a boron compound particles, whose average diameter dis at least about 2 micrometers, the SiC particles content being more than 90% by weight of the powder mixture; b) co-milling the powder mixture until the overall average diameter dof the resulting particles is between 0.3 and 1 micrometers; c) chemically treating the powder mixture by base solution and acid wash; d) mixing the powder mixture of c) with 1 to 10% by weight, based upon the silicon carbide content, of a carbon containing resin having a water miscibility of more than 10:50, as measured according to the ISO8989 standard, and e) spray-drying the resulting mixture of d), to generate the granules.
