Product Description
XICRU™ HT Series Crucibles for Zinc Oxide Distillation & Copper Alloy Processing – 900–1400°C, Gray Anti-Oxidation Coating, Up to Ø1525 mm × 1050 mm.
XICRU™ HT Series Crucibles are premium isostatic pressed crucibles manufactured from advanced Sialon (Si₃Al₃O₃N₅) and sintered silicon carbide ceramics, specially developed for the extreme conditions of zinc oxide distillation and high-temperature smelting of copper, gold, silver, and rare metals.
The HT Series (Gray) receives an additional layer of anti-oxidation coating for enhanced protection in oxidizing atmospheres, without a second firing. This delivers superior thermal stability, chemical inertness, low porosity, high mechanical strength, and excellent non-wetting properties – ensuring long service life, minimal metal contamination, and drastically reduced maintenance. Operating temperature range: 900–1400 °C.
Maximum size: Ø1525 mm × height 1050 mm – among the largest available for industrial-scale processes. These crucibles offer the best price/performance ratio, fast heat-up, low energy consumption, and seamless integration with XICAR™ SiC components and Sialon ULTRA™ systems. Ideal for demanding metallurgy where purity and durability are critical.
Since 1986, Sialon Ceramics has supplied these HT Series crucibles to foundries worldwide, providing reliable performance in the harshest high-temperature environments with minimal downtime.
