High-purity 3N5 (99.95%) / 4N (99.99%) Electron-Beam Melted (RO5200 / RO5400) High-Purity tantalum (ta) crucibles, boats & chemical liners (Ta, CAS 7440-25-7) engineered for ultra-high-temperature vacuum furnaces, crystal growth, semiconductor processing, and corrosive environments.
Consolidated by powder metallurgy, vacuum arc remelting (VAR), or electron-beam melting and stress-relieved for high-temperature dimensional stability, our High-Purity tantalum (ta) crucibles, boats & chemical liners (Ta, CAS 7440-25-7) products deliver reliable performance in vacuum, inert-gas, and reducing furnace atmospheres.
Combining a 3,017 °C melting point with glass-like immunity to boiling HCl, HNO3, H2SO4, and liquid lanthanide metals, tantalum crucibles excel in rare-earth metallurgy, SiC crystal growth, and corrosive chemical processing. Every shipment includes the producing mill's chemical purity Certificate of Analysis (reporting metallic and interstitial O, N, C, H trace levels in ppm) and pre-shipment dimensional verification.
