Tungsten Crucible in Rare Earth Smelting
Tungsten crucible in rare earth smelting is a high-temperature vessel used in melting, reduction, purification, and reaction processing of rare earth metals and related compounds. It provides stable containment for rare earth melts under high-temperature vacuum or inert atmosphere while maintaining stable thermal distribution for reaction systems.
CTIA’s tungsten crucible is fabricated from high-purity tungsten with a purity of W≥99.95% through powder metallurgy sintering, densification forming, and precision machining processes, meeting the requirements of rare earth smelting for high-temperature stability and low contamination environments.
Why Is CTIA’s Tungsten Crucible Used in Rare Earth Smelting?
Rare earth smelting typically involves high-temperature and chemically active environments, requiring crucibles with reliable thermal stability and chemical resistance. CTIA’s tungsten crucible offers the following features for stable rare earth processing:
(1) Excellent high-temperature stability: Suitable for high-temperature rare earth melting and reduction processes;
(2) Reliable structural stability: Maintains good dimensional accuracy and structural integrity during long-term high-temperature operation;
(3) Good chemical resistance: Compatible with most rare earth molten salt and oxide systems;
(4) Stable thermal conductivity: Helps improve melt temperature uniformity and reaction consistency;
(5) Good thermal shock resistance: Suitable for rapid heating and cooling conditions;
(6) Low contamination: High-purity tungsten substrate helps reduce impurity introduction and improve rare earth material purity.
