High-purity ASTM B551 Zr 702 (99.2% Zr+Hf) & Low-Hafnium 3N5 (<100 ppm Hf) Research Grade zirconium (zr 702 & Low-Hf 3N5) crucibles, foil, sheet, rod & wire (Zr, CAS 7440-67-7) 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 zirconium (zr 702 & Low-Hf 3N5) crucibles, foil, sheet, rod & wire (Zr, CAS 7440-67-7) products deliver reliable performance in vacuum, inert-gas, and reducing furnace atmospheres.
Zirconium laboratory crucibles withstand molten sodium peroxide (Na2O2) and sodium carbonate fusions that rapidly destroy platinum and porcelain labware, while low-Hf zirconium foil serves nuclear, X-ray filter, and getter research. 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.
