Silicon Carbide - an overview | ScienceDirect Topics
Coarser grades (> 10 μm) of silicon carbide powder cannot be sintered to high density. For refractory appliions, compacted coarse silicon carbide grit in the required shape is bonded using a bonding phase of, for example, silicon nitride or nitride oxide, aluminosilie glass, or self-bonded carbon and silicon.

Silicon carbide — Wikipedia Republished // WIKI 2
Pure silicon carbide can be made by the Lely process, in which SiC powder is sublimed into high-temperature species of silicon, carbon, silicon dicarbide (SiC 2), and disilicon carbide (Si 2 C) in an argon gas aient at 2500 C and redeposited into flake-like single crystals, sized up to 2×2 cm, at a slightly colder substrate.
