Tungsten Crucible

Key Advantages

Precision Customization: Need specific sizes (OD 10 – 500mm, height 10 – 750mm), production methods (sintering/stamping)? We tailor tungsten crucibles for your use—sapphire crystal growth, quartz glass melting, rare – earth smelting, etc. Small batches welcome for testing.
Quality Assurance: Undergo strict testing (chemical, mechanical, X – ray, appearance). Low impurity levels (single element ≤0.01%, total ≤0.05%)—ensures reliability in extreme environments (≥2000°C).
Industry – Critical Performance: High temp strength, wear/corrosion resistance—supports industrial furnace core containers in sapphire, quartz, and rare – earth industries.

Primary Applications

Sapphire Growth Furnaces: High – temp containers—supports crystal growth at extreme temperatures.
Quartz Glass Melting: Corrosion – resistant crucibles—withstands reactive molten glass.
Rare – Earth Smelting: Thermal – stable components—ensures uniform heating and material integrity.

Testing

Chemical composition test (purity, impurity control)
Mechanical properties test (strength, hardness)
Appearance size detection (dimensional accuracy)
X – ray detection (internal structure integrity)

Packaging & Delivery

Packaging: Pearl cotton + wooden cases—protects against collision, ensures product integrity.
Shipping: Global delivery via trusted couriers. Contact us for lead times—we align with your production schedule.
