Product Description
XICAR™ SSiC Sintered Silicon Carbide Crucibles – Up to 1900°C, HEXOLOY® Alternative, Large Sizes to Ø1525 mm for Extreme High-Temperature Melting.
XICAR™ SSiC Sintered Silicon Carbide Crucibles are premium high-temperature technical ceramics manufactured from pressureless-sintered silicon carbide (SSiC). They deliver unmatched performance in the most demanding molten non-ferrous applications, withstanding 1700 °C in air and 1900 °C in controlled atmospheres. Ideal for zinc oxide distillation, melting copper, gold, aluminium, zinc alloys, and laboratory R&D processes where extreme heat, chemical erosion, and thermal shock resistance are critical.
These crucibles offer superior chemical corrosion resistance, high mechanical hardness, excellent thermal conductivity, and thermal stability – often equivalent to HEXOLOY® SE. Very large sizes are possible (up to Ø1525 mm and lengths to 3000 mm), making them suitable for industrial-scale melting while maintaining non-wetting properties and long service life with minimal maintenance.
Key advantages include:
- Exceptional thermal shock resistance
- High purity and low porosity
- Outstanding wear and erosion resistance
- Best price/performance ratio for ultra-high-temperature containment
They complement the full XICAR™ range (thermocouple tubes, custom components) and integrate seamlessly with Sialon ULTRA™ products in mixed foundry setups. Since 1986, Sialon Ceramics has specialised in these advanced materials for the molten non-ferrous industry. View XICAR™ SSiC Crucibles – custom shapes, sizes, and lids available on request. Quality warranty included.
XICAR™ Sintered Silicon Carbide (SSiC) is the toughest high-temperature ceramic we offer. Operating up to 1900 °C, it matches HEXOLOY® while giving the best price/performance ratio.
