Product Description
XICAR™ Custom Sintered Silicon Carbide (SSiC) Components – Any Shape, Up to 3000 mm Long, 1900°C Max, HEXOLOY® SE Alternative XICAR™ Custom Sintered Silicon Carbide Products are fully bespoke high-performance components made from premium pressureless-sintered SiC (SSiC). They are engineered to your exact drawings and specifications for the most extreme high-temperature and corrosive environments.
Maximum size: length up to 3,000 mm, outer diameter up to 300 mm. Operating temperature: 1,700 °C in air and 1,900 °C in controlled atmosphere. These parts offer exceptional chemical corrosion resistance, high mechanical hardness, outstanding thermal conductivity, low porosity, and superior thermal shock resistance – making them the toughest, most cost-effective alternative to Saint-Gobain HEXOLOY® SE.
Typical custom applications include:
- Special thermocouple protection tubes
- Burner nozzles
- Wear plates & liners
- Pump components
- Seals & bearings
- Furnace fixtures
- Any complex shape that standard tubes or crucibles cannot cover
