What's the difference between reaction bonded silicon carbide (RBSC) and pressureless sintered silicon carbide (PLSSC)?

2026-01-28
What's the difference between reaction bonded silicon carbide (RBSC) and pressureless sintered silicon carbide (PLSSC)?

1. Process: RBSC forms via reaction bonding with residual silicon; PLSSC sinters at high temp without external pressure.
2. Density & Porosity: RBSC is low-density with porosity; PLSSC is high-density, almost fully dense.
3. Performance: RBSC has good impact resistance; PLSSC excels in hardness, corrosion resistance and high-temperature stability.
4. Cost: RBSC is cost-effective; PLSSC is more expensive due to complex process.
