Tantalum crucible

I. Product Introduction Tantalum crucibles are high-temperature resistant containers made from high-purity tantalum (R05200, R05400, ≥99.95%) through stamping, deep drawing, spinning, welding, or machining, followed by high-temperature annealing and pickling finishing.

Tantalum possesses extremely high melting points, exceptional chemical stability, good high-temperature strength, and does not react with most molten metals, making tantalum crucibles crucial high-temperature vessels in advanced metallurgy, crystal growth, and scientific research experiments.

Core Performance

Melting Point: 2996℃, high-temperature creep resistant, not easily deformed

Density: 16.69 g/cm³, dense structure, non-porous

Corrosion Resistance: Resistant to strong acids, strong alkalis, aqua regia; resistant to most molten salts and metal corrosion at high temperatures

High purity, low volatility, does not contaminate the melt, suitable for high-purity material preparation

Can be integrally molded or welded, good airtightness, long service life

Common Specifications
