Product Description

Product Description

TANTALUM CRUCIBLE

The Tantalum Crucible boasts an array of extraordinary properties including a high melting point, minimal vapor pressure, outstanding cold processing capabilities, exceptional chemical stability, and a robust resistance to corrosion from liquid metals. Additionally, it exhibits a high dielectric constant of its surface oxide film. This makes it an indispensable tool in various high-stakes environments: from sintering sapphire and operating in arc furnaces to serving as sophisticated containers under challenging conditions. Notably, tantalum crucibles are optimal for the melting of sapphire.

Tantalum's unique attributes of an elevated melting point combined with remarkable chemical stability make it indispensable during sapphire smelting, primarily composed of alumina. The crucible sustains extreme temperatures while minimizing the risk of contaminating sapphire raw materials, thus maintaining a pristine setting conducive to sapphire growth. It is critical to meticulously manage process conditions to leverage the crucible's full potential, ensuring the successful production of high-quality sapphire.

HIGH MELTING POINT AND HIGH TEMPERATURE RESISTANCE:

With a melting point soaring to an impressive 2996ºC, tantalum stands as the fifth highest among single substances. This characteristic endows the tantalum crucible with unmatched stability in high-temperature environments, enabling it to meet stringent temperature demands across material melting, sintering, and other intensive heat treatments. It is particularly suited for rare earth smelting and high-temperature sintering applications.

EXCELLENT CHEMICAL STABILITY:

Tantalum exhibits remarkable resilience at room temperature, showing no reaction to hydrochloric acid and aqua regia, alongside high resistance to numerous corrosive agents. This makes tantalum tubes ideal for transporting corrosive liquids and gases in the chemical industry. However, caution is advised as tantalum will succumb to corrosion in hot concentrated sulfuric acid, fuming sulfuric acid, and high-temperature phosphoric acid, though its corrosion resistance remains formidable within specific temperature ranges.

GOOD DEFORMATION RESISTANCE:

Featuring an exceptionally low thermal expansion coefficient-only 6.6ppm per degree Celsius-tantalum is endowed with significant toughness, minimizing deformation even amidst temperature fluctuations. It maintains superior dimensional stability, crucial for ensuring the accuracy and repeatability of experimental or manufacturing processes.

GOOD PROCESSING PERFORMANCE:

Striking a balance between hardness and ductility, tantalum can be effortlessly drawn into filaments or transformed into thin foils. This versatility allows tantalum crucibles to be tailored into diverse shapes and sizes, satisfying the specifications of varied application scenarios.

REUSABILITY:

When proper usage and maintenance protocols are observed, tantalum crucibles can be reused multiple times, significantly cutting down on operational costs and enhancing sustainability.
