HIGH MELTING POINT AND HIGH TEMPERATURE RESISTANCE:

With an impressive melting point soaring to 2996ºC, tantalum stands as the fifth highest among single elements. This grants the tantalum crucible unparalleled stability even in extreme high-temperature environments, meeting the rigorous demands of material melting, sintering, and diverse high-temperature processes. It is an indispensable tool in rare earth smelting and high-temperature sintering, amongst other applications, where enduring heat resistance is paramount.

EXCELLENT CHEMICAL STABILITY:

Tantalum tubes triumph over corrosive challenges, remaining unresponsive to hydrochloric acid and aqua regia at ambient temperatures, with formidable resistance to numerous other corrosive substances. In the chemical industry, tantalum tubes are adept at transporting a spectrum of corrosive liquids and gases. While it can succumb to hot concentrated sulfuric, fuming sulfuric, and high-temperature phosphoric acids, its resistance remains robust within certain temperature limits.

GOOD DEFORMATION RESISTANCE:

Boasting an exceptionally small thermal expansion coefficient of just 6.6ppm per °C, tantalum exhibits outstanding toughness, ensuring that the crucible retains its form despite temperature fluctuations. This dimensional stability is crucial for ensuring experimental accuracy and process repeatability, providing consistent performance every time.

GOOD PROCESSING PERFORMANCE:

With its optimal balance of hardness and ductility, tantalum is a material of choice for crafting into filaments or thin foils. This adaptability allows tantalum crucibles to be fashioned into a variety of custom shapes and sizes, precisely meeting the demands of specific applications.

REUSABILITY:

When properly maintained, tantalum crucibles boast impressive reusability, significantly lowering operational costs by extending the lifecycle of the crucible across numerous applications.
