Specification of Sintered Pure Tungsten Crucible for Melting Rare Earth Metal

The sintered pure tungsten crucible is designed for melting rare earth metals in high-temperature industrial applications. The crucible is made from 99.95% pure tungsten powder. It undergoes high-temperature sintering to achieve optimal density and structural integrity. The material density exceeds 18.5 g/cm³. This ensures resistance to thermal stress and deformation during repeated heating cycles. The crucible operates effectively in environments up to 2000°C under vacuum or inert gas. It maintains stability in extreme conditions without cracking or warping.

The product features low thermal expansion and high thermal conductivity. These properties enable rapid heat transfer while minimizing thermal fatigue. The crucible’s chemical inertness prevents reactions with rare earth metals like lanthanum, cerium, or neodymium. This reduces contamination risks during melting processes. The smooth internal surface minimizes material adherence. This simplifies post-use cleaning and extends service life.

Standard crucible dimensions range from 50 mm to 300 mm in diameter. Custom sizes and shapes are available for specialized furnace setups. Wall thickness varies between 3 mm and 10 mm. Thicker walls enhance durability for prolonged high-temperature use. Thinner walls improve heat efficiency for faster melting. The crucible’s cylindrical design ensures uniform heat distribution. Optional conical shapes cater to specific pouring requirements.

Production involves powder compaction and sintering at over 2000°C. This eliminates porosity and enhances mechanical strength. Each crucible undergoes rigorous quality checks. Tests include ultrasonic flaw detection and dimensional accuracy verification. The product meets ISO 9001 standards for material consistency and performance reliability.

Packaging uses vacuum-sealed materials to prevent oxidation during storage and transport. Handling guidelines emphasize using dry gloves to avoid surface contamination. The crucible is compatible with induction heating systems and resistance furnaces. It is suitable for vacuum melting, crystal growth, and alloy production. Proper maintenance involves cooling to room temperature before handling. Avoid sudden temperature changes to prevent thermal shock.

The sintered tungsten crucible offers long-term cost efficiency. It reduces downtime linked to frequent replacements. Industrial users in aerospace, electronics, and metallurgy benefit from its high-temperature resilience. Customization options include surface polishing for reduced metal adhesion.

Applications of Sintered Pure Tungsten Crucible for Melting Rare Earth Metal

Sintered pure tungsten crucibles serve critical roles in high-temperature processes involving rare earth metals. These crucibles withstand extreme heat due to tungsten’s exceptionally high melting point. Rare earth metals require melting temperatures often exceeding 1500°C. Ordinary materials fail under such conditions. Tungsten’s stability ensures minimal contamination during melting. This is vital for producing high-purity rare earth alloys used in advanced technologies.

The sintering process creates dense, durable structures. Traditional casting methods leave pores or impurities. Sintered tungsten crucibles avoid these issues. They maintain structural integrity even after repeated thermal cycles. This reduces downtime and replacement costs in industrial settings.

Rare earth metals react easily with oxygen and other elements. Tungsten’s corrosion resistance prevents unwanted reactions. It keeps molten metals pure. Industries like aerospace and electronics rely on this purity. Components made from these metals demand exact material properties. Even slight impurities compromise performance.

Vacuum environments are common in rare earth metal processing. Tungsten crucibles perform reliably under low-pressure conditions. They resist warping or cracking. Graphite or ceramic alternatives often degrade faster. Tungsten’s longevity makes it cost-effective for large-scale operations.

The crucibles suit induction melting systems. Tungsten efficiently conducts heat while resisting electrical currents. This compatibility streamlines industrial workflows. Manufacturers achieve consistent results without adjusting equipment settings.

High-energy physics and nuclear applications also use these crucibles. Tungsten handles radioactive or reactive materials safely. Its radiation shielding properties add value in specialized research. Laboratories prioritize safety and precision. Sintered tungsten crucibles meet both requirements.

Metallurgical industries benefit from tungsten’s wear resistance. Continuous use in harsh environments does not erode the crucible walls. Maintenance needs stay low. Production schedules remain uninterrupted.

Semiconductor manufacturing requires ultra-clean materials. Tungsten crucibles prevent contamination during silicon or gallium processing. Finished semiconductors power devices from smartphones to solar panels.

Tungsten’s thermal conductivity ensures even heat distribution. Hot spots or uneven melting rarely occur. This uniformity improves product quality. Manufacturers reduce waste and increase yield.

Customizable sizes and shapes adapt to specific industrial needs. Users optimize furnace space and material usage. Flexibility supports diverse applications without compromising performance.

Sintered pure tungsten crucibles address challenges in handling rare earth metals. Their durability, purity, and thermal properties make them indispensable across high-tech sectors.

5 FAQs of Sintered Pure Tungsten Crucible for Melting Rare Earth Metal

What is a sintered pure tungsten crucible?
A sintered pure tungsten crucible is a container made by compacting tungsten powder under high heat and pressure. This process creates a dense, durable material ideal for high-temperature applications. The crucible resists cracking and maintains structural stability even under extreme conditions. It is commonly used in melting rare earth metals due to its reliability.

Why choose tungsten for melting rare earth metals?
Tungsten has a melting point above 3,400°C, higher than most metals. Rare earth metals require extreme heat to melt, and tungsten crucibles handle this without deforming. Tungsten also resists chemical reactions with rare earth elements. This prevents contamination during melting. The material’s strength ensures long-term use in harsh environments.

What temperature can a sintered tungsten crucible withstand?
These crucibles operate reliably at temperatures up to 2,000°C in inert or vacuum environments. Exceeding this range risks gradual wear or surface damage. The exact limit depends on the crucible’s purity and sintering quality. Proper temperature control extends its lifespan. Always follow manufacturer guidelines for safe operation.

How long does a sintered tungsten crucible last?
Lifespan varies based on usage conditions. Frequent exposure to extreme heat or rapid cooling cycles may reduce durability. Proper handling and avoiding mechanical shocks help maintain integrity. With regular maintenance, a high-quality crucible can last months or years. Inspect it periodically for cracks or erosion.

Can sintered tungsten crucibles be customized?
Yes. Manufacturers offer customization for size, wall thickness, and shape to fit specific furnace setups. Special surface treatments or additional coatings are available for enhanced performance. Provide detailed requirements to ensure the crucible meets your application’s needs. Custom designs may require longer production times.
