Claim Text:
1. A process for obtaining granules useful for the manufacture of a silicon carbide based sintered product, comprising: a) mixing a first powder of silicon carbide SiC particles, whose average diameter d b) co-milling the powder mixture of SiC and boron compound particles until the overall average diameter D c) chemically treating the powder mixture at least by base solution and then by acid wash; d) mixing the powder mixture coming from step 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 from step d), so as to generate said granules.
