Product Description

Product Description

TANTALUM CRUCIBLE

The tantalum crucible is marvelously designed with a host of exceptional characteristics that make it indispensable. Its high melting point, impressive resistance to vapor pressure, and excellent cold processing capabilities are complemented by its remarkable chemical stability and strong defense against liquid metal corrosion. Furthermore, the high dielectric constant of its surface oxide film ensures superior performance. This crucible finds extensive applications in the sintering of sapphire, as well as serving as a reliable container for arc furnaces and other complex processing scenarios. It is particularly ideal for the melting of sapphire due to these inherent properties.

Known for its high melting point and chemical stability, tantalum is a superior material choice for sapphire smelting, primarily composed of alumina. It effectively withstands the extreme temperatures required while minimizing the risk of contaminating the sapphire raw materials. This guarantees a pristine environment for the growth of sapphire. However, to fully harness the crucible's potential and ensure the production of high-quality sapphire, meticulous control of the process conditions is essential during use.

HIGH MELTING POINT AND HIGH TEMPERATURE RESISTANCE:

Boasting a melting point soaring to 2996ºC, tantalum ranks fifth among single elements for its heat resilience, making these tantalum crucibles exceptionally stable in high-temperature environments. They can effortlessly meet the rigorous temperature demands of material melting, sintering, and other high-temperature treatment processes. As such, they are perfectly suited for rare earth smelting, high-temperature sintering, and more.

EXCELLENT CHEMICAL STABILITY:

Tantalum's chemical stability is unparalleled at room temperature. It remains unreactive with hydrochloric acid and aqua regia, and it shows commendable resistance to a variety of other corrosive media. In the chemical industry, tantalum tubes are essential for the safe transport of corrosive liquids and gases. Although tantalum may corrode in hot concentrated sulfuric acid, fuming sulfuric acid, and high-temperature phosphoric acid, its corrosion resistance remains remarkable within certain temperature thresholds.

GOOD DEFORMATION RESISTANCE:

Tantalum's incredibly low thermal expansion coefficient, expanding merely 6.6ppm per degree Celsius, coupled with its strong toughness, ensures that the tantalum crucible remains structurally sound even with temperature fluctuations. This stability is crucial for maintaining accurate and repeatable results, whether in experimental or industrial processes.

GOOD PROCESSING PERFORMANCE:

With a perfect balance of hardness and ductility, tantalum is remarkably versatile. It can be crafted into filaments or thin foils, allowing for the tantalum crucibles to be seamlessly fashioned into various shapes and sizes to cater to diverse application needs.

REUSABILITY:

When used and maintained with care, tantalum crucibles can be reused multiple times, significantly lowering the overall cost of use and making them a cost-effective solution.
