Reaction Bonded Silicon Carbide (RBSC/SiSiC) | High-Performance Commercial Components
Reaction Bonded Silicon Carbide (SiSiC) offers superior corrosion resistance, high-temperature strength, and wear resistance for demanding commercial applications. Compare its performance against other materials.
Reaction Bonded Silicon Carbide (SiSiC) for Commercial and Industrial Applications
Reaction Bonded Silicon Carbide (also known as Reaction Sintered or SiSiC) is an advanced structural ceramic manufactured by infiltrating a porous carbon and silicon carbide preform with molten silicon at over 1600°C. The resulting material contains 10-12% free silicon, delivering an exceptional combination of properties ideal for challenging environments. It is characterized by its ability to be formed into complex, near-net-shape components with minimal dimensional change during sintering.
Key Characteristics and Advantages
  • Superior Corrosion Resistance: Excellent resistance to a wide range of acids, alkalis, and other corrosive media, outperforming many metals and other ceramics.
  • High-Temperature Stability: Maintains strength and form at elevated temperatures.
  • Exceptional Wear Resistance: Ideal for components subject to abrasion and erosion.
  • Low Friction Coefficient: Reduces energy loss in moving applications.
  • Complex Geometries: Can be manufactured into intricate parts with minimal post-sintering dimensional change.
Corrosion Resistance Comparison
The following table details the corrosive weight loss (mg/cm²yr) of Reaction Bonded SiC compared to other common engineering materials in various harsh environments. Lower values indicate better corrosion resistance.
Test Environment Concentration (wt%) Temp. (°C) Sintered SiC (No Free Si) Reaction Bonded SiC (12% Si) Tungsten Carbide (6% Co) Aluminum Oxide (99%)
Sulfuric Acid 98% H₂SO₄ 100 1.8 55.0 >1000 65.0
Sodium Hydroxide 50% NaOH 100 2.5 > 1000 5.0 75.0
Hydrofluoric Acid 53% HF 25 <0.2 7.9 8.0 20.0
Phosphoric Acid 85% H₃PO₄ 100 <0.2 8.8 55.0 >1000
Nitric Acid 70% HNO₃ 100 <0.2 0.5 >1000 7.0
Potassium Hydroxide 45% KOH 100 <0.2 > 1000 3.0 60.0
Hydrochloric Acid 25% HCl 70 <0.2 0.9 85.0 72.0
Mixed Acid 10% HF + HNO₃ 25 <0.2 > 1000 >1000 16.0
Material Selection Insights
  • For Acidic Environments: RBSC shows excellent resistance to nitric and hydrochloric acids and good resistance to phosphoric acid. Note that it is attacked by hydrofluoric acid and mixed acids containing HF.
  • For Alkaline Environments: RBSC is generally not recommended for hot, concentrated caustic solutions (like NaOH and KOH), where it shows significant weight loss.
  • Comparative Performance: RBSC often provides a more balanced chemical resistance profile compared to Tungsten Carbide (which can fail in oxidizing acids) and Alumina (which is vulnerable to strong acids and alkalis).
