Reaction Bonded Silicon Carbide Sheet (SiSi)

Reaction Bonded Silicon Carbide (SiSiC) Sheet offers high stiffness, extreme hardness, and resistance to chemical attack in a flat panel format suited to structural, thermal, and protective applications. Its fine-grained microstructure provides excellent dimensional stability, making it ideal for precision tooling, thermal shields, and wear plates. Industries use SiSiC sheets in semiconductor wafer handling systems, heat-resistant conveyor plates, and armor components. Specific applications include corrosion-proof liner panels in chemical vessels, high-temperature heat exchanger baffles, and protective facing in ballistic systems. In research, SiSiC sheets are used to evaluate erosion resistance under particle impact, study thermal conductivity at elevated temperatures, and develop hybrid ceramic-metal structures. The sheet format’s combination of mechanical integrity and thermal resilience ensures broad use in industrial and high-technology sectors.
