Product Description

Product Description

TANTALUM CRUCIBLE

The tantalum crucible is a marvel of engineering, boasting a suite of remarkable properties that make it indispensable in industrial applications. With its high melting point and low vapor pressure, it excels in durability and performance. Its superior cold processing capabilities and exceptional chemical stability ensure that it stands strong against liquid metal corrosion. The tantalum crucible's surface oxide film features a high dielectric constant, reinforcing its outstanding reputation. This innovative product is widely embraced in the manufacturing of sintering sapphire container crucibles and arc furnace container crucibles. It is a vital component in various complex containers demanding rigorous processing conditions and is perfectly suited for melting sapphire.

Tantalum is renowned for its exemplary high melting point and exceptional chemical stability. During sapphire smelting, where alumina is the primary component, tantalum crucibles excel by enduring extreme temperatures while minimizing contamination risks. This ensures a pristine environment essential for sapphire's growth. However, to maximize the crucible's performance, meticulous control of process conditions is paramount, allowing it to achieve the successful melting of top-tier sapphire.

HIGH MELTING POINT AND HIGH TEMPERATURE RESISTANCE:

With a melting point soaring to 2996ºC, tantalum ranks fifth among single substances, underscoring its robust stability in extreme heat. It effortlessly meets the demanding temperature conditions required for the melting, sintering, and high-temperature treatment of various materials. This makes it an ideal choice for rare earth smelting, high-temperature sintering, and numerous other demanding scenarios.

EXCELLENT CHEMICAL STABILITY:

At ambient temperatures, tantalum exhibits remarkable resilience, remaining unreactive to both hydrochloric acid and aqua regia, as well as numerous other corrosive media. In the chemical industry, tantalum tubes are invaluable for transporting corrosive liquids and gases. While they may corrode in hot concentrated sulfuric acid, fuming sulfuric acid, and high-temperature phosphoric acid, their superior resistance remains noteworthy within specific temperature ranges.

GOOD DEFORMATION RESISTANCE:

Tantalum's exceptionally low thermal expansion coefficient, just 6.6ppm per degree Celsius, coupled with its robust toughness, endows it with impressive resistance to deformation despite temperature fluctuations. This ensures that the tantalum crucible maintains its dimensional stability, safeguarding the precision and consistency of both experimental and production processes.

GOOD PROCESSING PERFORMANCE:

Striking a balance between hardness and ductility, tantalum can be expertly drawn into filaments and fashioned into thin foils. This versatility allows tantalum crucibles to be crafted into diverse shapes and sizes, catering to varied application needs with ease.

REUSABILITY:

When maintained and used correctly, tantalum crucibles can be reused multiple times, significantly cutting down on operational costs and enhancing economic efficiency.
