Product Description

Product Description

TANTALUM CRUCIBLE

The tantalum crucible is a marvel of modern metallurgy, boasting a blend of remarkable properties such as its exceptionally high melting point, minimal vapor pressure, superlative cold processing capabilities, and superior chemical stability. It demonstrates a robust resistance to corrosion by liquid metals and possesses a high dielectric constant in its surface oxide film. These attributes make it an indispensable tool in diverse applications, including sapphire sintering container crucibles, arc furnace container crucibles, and an array of containers designed for intricate processing and demanding use conditions. Notably, the tantalum crucible is ideally suited for the melting of sapphire, ensuring precision and purity in every application.

Tantalum's extraordinary high melting point and outstanding chemical stability make it an ideal choice for sapphire smelting, where temperatures soar, and the main component, alumina, prevails. The minimal risk of contaminating raw sapphire materials ensures a pristine environment conducive to sapphire growth. However, meticulous control of process conditions is paramount to fully leverage the crucible's performance, guaranteeing the successful melting of superior quality sapphire.

HIGH MELTING POINT AND HIGH TEMPERATURE RESISTANCE:

With an impressive melting point of 2996ºC, tantalum ranks fifth among single substances, endowing the tantalum crucible with unrivaled stability in extreme high-temperature environments. It meets the rigorous temperature demands of material melting, sintering, and a myriad of high-temperature treatment processes. This makes it an invaluable asset in rare earth smelting, high-temperature sintering, and other specialized scenarios requiring robust temperature resistance.

EXCELLENT CHEMICAL STABILITY:

Tantalum stands firm against reactive forces at room temperature, showing remarkable resilience to hydrochloric acid, aqua regia, and numerous other corrosive substances. In the chemical industry, tantalum tubes serve as conduits for corrosive liquids and gases. Despite this, caution is advised with hot concentrated sulfuric acid, fuming sulfuric acid, and high-temperature phosphoric acid, where corrosion is possible. Nevertheless, tantalum's corrosion resistance remains formidable within specific temperature thresholds.

GOOD DEFORMATION RESISTANCE:

Tantalum's minimal thermal expansion, with a mere 6.6ppm per degree Celsius, coupled with its robust toughness, ensures the tantalum crucible remains steadfast against deformation during temperature fluctuations. This stability is critical in maintaining dimensional precision and consistency, vital for experimental accuracy and production reliability.

GOOD PROCESSING PERFORMANCE:

Tantalum's balanced hardness and ductility allow it to be exquisitely drawn into filaments or fashioned into thin foils, facilitating the crafting of tantalum crucibles into myriad shapes and sizes to cater to diverse application requirements, enhancing their versatility and functionality.

REUSABILITY:

When properly cared for and maintained, tantalum crucibles offer exceptional reusability, significantly reducing operational costs and optimizing efficiency across multiple use cycles.
