Our silicon carbide foam ceramics and solid components demonstrate exceptional chemical resistance across various environments. Testing shows minimal corrosion rates: 0.04 mg/cm²/year in 70% HNO₃ at 100°C and 0.07 mg/cm²/year in 37% HCl at 86°C. This superior chemical stability makes our products ideal for harsh industrial applications.
The low apparent porosity (≤0.05 Vol%) ensures excellent chemical barrier properties. Our wholesale cu silicon carbide semiconductor ceramics customized solutions include special surface treatments for enhanced chemical resistance when required for specific applications.
