Product Description

Product Description

TANTALUM CRUCIBLE

Our tantalum crucible is engineered with an array of exceptional properties, making it indispensable in demanding industrial applications. With its notably high melting point, low vapor pressure, and superior cold processing capabilities, this product assures outstanding chemical stability and robust resistance to liquid metal corrosion. The high dielectric constant of its surface oxide film further enhances its versatility. Ideally suited for container crucibles in sapphire sintering and arc furnaces, it thrives in environments requiring stringent and complex processing conditions. Its proficiency extends to effectively melting sapphire, a testament to its unmatched quality.

The intrinsic properties of tantalum, most notably its high melting point and unparalleled chemical stability, make it an ideal choice for the sapphire smelting process. Given that sapphire primarily consists of alumina, the tantalum crucible endures high-temperature environments while ensuring minimal contamination. This facilitates an impeccably pure environment crucial for sapphire growth. To maximize the crucible's capabilities and achieve superior quality sapphire, it is imperative to maintain strict control over process conditions during its application.

HIGH MELTING POINT AND SUPERIOR TEMPERATURE RESISTANCE:

Boasting a remarkable melting point of 2996ºC, tantalum stands prominently among elements, ranking fifth in single substances. This incredible thermal stability allows the tantalum crucible to excel in high-temperature environments. It meets the stringent requirements of material melting, sintering, and other demanding high-temperature processes, making it particularly suitable for rare earth smelting and high-temperature sintering scenarios.

EXCEPTIONAL CHEMICAL STABILITY:

At ambient temperatures, tantalum exhibits non-reactivity to hydrochloric acid and aqua regia, showcasing impressive resistance against a variety of corrosive media. This makes tantalum tubes valuable in the chemical industry for transporting corrosive liquids and gases. While tantalum can corrode in hot concentrated sulfuric acid, fuming sulfuric acid, and high-temperature phosphoric acid, its corrosion resistance remains commendable within certain temperature limits.

OUTSTANDING DEFORMATION RESISTANCE:

Tantalum's minimal thermal expansion coefficient, only 6.6ppm per degree Celsius, coupled with its robust toughness, ensures the crucible maintains its shape and dimensional stability amidst temperature fluctuations. This characteristic is vital in upholding the accuracy and consistency of experimental and production processes.

EXCELLENT PROCESSING PERFORMANCE:

With its balanced hardness and ductility, tantalum is easily drawn into filaments or crafted into thin foils. This versatility permits the shaping of tantalum crucibles into various forms and dimensions, perfectly aligning with diverse application requirements.

SUSTAINABLE REUSABILITY:

When proper use and maintenance protocols are followed, tantalum crucibles demonstrate impressive reusability, significantly cutting down on operational costs and enhancing economic efficiency.
