Stability of silicon carbide to hydrofluoric, nitric, and sulfuric acids …

When the preparation temperature of β -SiC is decreased, its decomposition is enhanced. The greatest decomposition (30–55%) is exhibited by β -SiC subjected to hydrofluoric acid containing sulfuric and nitric acids. The presence of impurities in β -silicon carbide retards its decomposition by acids. Download to read the full article text.

Ceramics for Corrosion Resistance - San Jose Delta

Silicone carbide resists both strong acids and strong bases. After 125 hours of submersion in HSO, it experienced a corrosive weight loss of only 0.21 x 103oz/in.yr (1.8 mg/cmyr) compared to 15 x 10 oz/in.2yr (65 mg/cmyr) for aluminum oxide, and more than 230 x 10oz/in.yr (1,000 mg/cmyr) for tungsten carbide.
