5 FAQs of Supply pure tungsten crucible 99.96% /Polished seamless pure tungsten crucible/ tungsten alloy

What is the significance of a 99.96% pure tungsten crucible?
A 99.96% purity ensures minimal impurities, critical for high-temperature applications where contamination risks must be eliminated. This grade of tungsten offers superior thermal stability, corrosion resistance, and durability, making it ideal for processes like semiconductor manufacturing, metallurgy, or crystal growth, where material integrity is non-negotiable.

What industries use polished, seamless tungsten crucibles?
These crucibles are widely used in aerospace, electronics, and advanced material research. They are essential for melting rare metals (e.g., titanium, platinum), growing synthetic crystals, or handling reactive chemicals. The polished surface reduces adherence of molten materials, while the seamless design enhances structural strength and longevity under extreme conditions.

Why choose a polished and seamless design?
Polishing minimizes surface irregularities, preventing material buildup and contamination during high-temperature processes. A seamless construction eliminates weak points caused by welding or joints, ensuring uniform heat distribution and resistance to thermal stress. This design is crucial for applications requiring consistent performance and extended crucible lifespan.

What temperature can a pure tungsten crucible withstand?
Pure tungsten crucibles withstand temperatures up to 3422°C (6192°F), the highest melting point among metals. They outperform alternatives like molybdenum (2610°C) or graphite (sublimes at 3600°C but oxidizes easily). Tungsten’s low thermal expansion and high thermal conductivity further ensure stability in rapid heating or cooling cycles.

How does a tungsten alloy crucible differ from pure tungsten?
Tungsten alloys may incorporate elements like nickel or iron to improve machinability or reduce costs, but this lowers melting points and thermal resistance. Pure tungsten crucibles (99.96%) prioritize unmatched heat tolerance and chemical inertness, ideal for extreme environments. Alloys are better suited for less demanding applications where mechanical workability is prioritized over maximum performance.

How should I maintain a tungsten crucible?
Avoid thermal shock by gradually heating or cooling. Clean with non-abrasive solvents or ultrasonic methods to preserve the polished surface. Store in a dry environment to prevent oxidation. Inspect regularly for micro-cracks, though pure tungsten’s hardness ensures minimal wear under proper use.
