A2: Pure silicon carbide is a semiconductor, meaning its electrical conductivity is intermediate between that of a conductor and an insulator. Its conductivity can be precisely controlled by doping during manufacturing, making it ideal for power electronics applications. Reaction-bonded SiC, due to its free silicon content, tends to be more electrically conductive than sintered SiC.

P3: Qual é a durabilidade dos componentes personalizados de SiC em ambientes abrasivos?

A3: Custom SiC components exhibit exceptional durability in abrasive environments due to their extreme hardness, which is second only to diamond. This makes them highly resistant to wear, erosion, and scratching, significantly extending the lifespan of parts like nozzles, pump seals, and wear plates compared to traditional metals or plastics.

Q4: Can custom SiC parts be repaired or re-coated?

A4: Repairing SiC parts is challenging due to their hardness and brittleness. Minor chips or surface wear might be addressed through re-grinding or re-lapping, but significant damage typically necessitates replacement. Re-coating is possible, especially for CVD SiC layers, to restore or enhance surface properties.
