HIGH MELTING POINT AND HIGH TEMPERATURE RESISTANCE:

With a melting point soaring up to 2996ºC, tantalum ranks fifth among single substances for melting point. This attribute guarantees the tantalum crucible's stability across high-temperature environments, making it an ideal choice for the melting, sintering, and treatment of demanding materials. It is particularly suited for rare earth smelting and high-temperature sintering scenarios, showcasing its versatility in extreme conditions.

EXCELLENT CHEMICAL STABILITY:

At ambient temperatures, tantalum exhibits extraordinary resistance to hydrochloric acid, aqua regia, and an array of other corrosive agents. Within the chemical industry, tantalum tubes are the go-to choice for transporting corrosive liquids and gases, thanks to their resilience. While it is vulnerable to corrosion in hot concentrated sulfuric, fuming sulfuric, and high-temperature phosphoric acids, tantalum maintains its formidable resistance below specific temperature thresholds.

GOOD DEFORMATION RESISTANCE:

Tantalum's minimal thermal expansion coefficient, expanding a mere 6.6ppm per degree Celsius, coupled with its robust toughness, ensures the crucible's dimensional stability amidst temperature fluctuations. This stability is crucial for maintaining accuracy and repeatability in both experimental and production settings.

GOOD PROCESSING PERFORMANCE:

Tantalum merges moderate hardness with ductility, allowing it to be expertly drawn into filaments or crafted into thin foils. This property enables tantalum crucibles to be meticulously processed into diverse shapes and sizes, catering to a wide spectrum of application needs.

REUSABILITY:

When subject to proper usage and maintenance, tantalum crucibles promise excellent reusability, significantly cutting down on operational costs and enhancing the product's value over time.
