Silicon Carbide | SiC | Ceramic | Supplier

Silicon carbide (SiC) is a synthetic, semiconducting fine ceramic that excels in a wide cross-section of industrial markets. Manufacturers benefit from an eclectic offering of silicon carbide grades due to the availability of both high-density and open porous structures.

Lely method - Wikipedia

The silicon carbide near the outer walls of the crucible sublimes and is deposited on a graphite rod near the center of the crucible, which is at a lower temperature. [2] Several modified versions of the Lely method exist, most commonly the silicon carbide is heated from the bottom end rather than the walls of the crucible, and deposited on the lid.

Effective optimization of surface passivation on porous …

Porous silicon carbide (B–N co-doped SiC) produced by anodic oxidation showed strong photoluminescence (PL) at around 520 nm excited by a 375 nm laser. The porous SiC samples were passivated by atomic layer deposited (ALD) aluminum oxide (Al 2 O 3) films, resulting in a significant enhancement of the PL intensity (up to 689%).
