Product Description

Product Description

TANTALUM CRUCIBLE

Tantalum crucibles are engineered with exceptional properties, including a remarkably high melting point, minimal vapor pressure, and outstanding cold processing performance. Their high chemical stability and robust resistance to liquid metal corrosion make them indispensable. Additionally, the high dielectric constant of their surface oxide film enhances their utility. These crucibles are extensively applied in sintering containers for sapphire, arc furnace crucibles, and various other demanding applications needing complex processing. They excel in melting sapphire, ensuring superior performance in challenging environments.

Tantalum stands out for its high melting point and superior chemical stability, making it ideal for sapphire smelting, primarily composed of alumina. It endures extreme temperatures while maintaining a low risk of contaminating sapphire raw materials, which is crucial for maintaining purity during sapphire growth. However, meticulous control over process conditions is vital to fully exploit the crucible's capabilities and achieve successful melting of high-grade sapphire.

HIGH MELTING POINT AND HIGH TEMPERATURE RESISTANCE:

With a melting point soaring to 2996ºC, tantalum ranks fifth among elemental substances, allowing the tantalum crucible to remain stable under extreme heat. It's capable of withstanding the thermal demands of material melting, sintering, and diverse high-temperature treatments, making it perfect for rare earth smelting and other intense heat scenarios.

EXCELLENT CHEMICAL STABILITY:

Tantalum tubes exhibit remarkable resistance to hydrochloric acid, aqua regia, and other corrosive media at room temperature. Even in the chemical industry, they safely transport a multitude of corrosive liquids and gases. Though they may corrode in hot concentrated sulfuric acid, fuming sulfuric acid, or high-temperature phosphoric acid, they still demonstrate outstanding corrosion resistance within specific temperature limits.

GOOD DEFORMATION RESISTANCE:

Tantalum boasts a minuscule thermal expansion coefficient, expanding just 6.6ppm per degree Celsius. Coupled with its robust toughness, the tantalum crucible resists deformation amidst temperature fluctuations, preserving dimensional stability. This ensures experimental or production precision and repeatability remain intact.

GOOD PROCESSING PERFORMANCE:

Tantalum's moderate hardness and ductility allow it to be drawn into filaments or fashioned into thin foils, enabling effortless customization of crucibles into diverse shapes and sizes to cater to varied application needs.

REUSABILITY:

When properly used and maintained, tantalum crucibles offer exceptional reusability, significantly reducing usage costs over time.
