High Purity 99.99% Iodide Hafnium Rod Crystalline Hf Crystal Bar for Nuclear Reactor Control Rods & Aerospace

Our High-Purity 99.99% Iodide Hafnium Rod (Crystalline Hf Crystal Bar) is manufactured using the premium iodide thermal dissociation process (Van Arkel-de Boer process). This high-density, low-impurity crystalline material exhibits exceptional thermal neutron absorption cross-sections and outstanding mechanical properties. Engineered for extreme operating conditions, it is the premier choice for nuclear reactor control rods, neutron shielding components, and next-generation aerospace superalloys.

Compliant with ASTM B737 / UNS R10001 international standards. A Mill Test Certificate (MTC) is provided with every batch.

• Nuclear Energy Engineering: Serving as high-efficiency neutron absorbers, extensively used in nuclear reactor control rods, safety shutdown rods, and reactor core structural materials, leveraging hafnium's exceptionally high neutron capture cross-section.
• Aerospace & Defense Alloys: Acting as a critical additive agent for nickel-based superalloys used in turbine blades, jet engines, and rocket nozzles, significantly enhancing high-temperature creep strength.
• Thin-Film Coatings: Serving as a premium evaporation source and sputtering target for advanced optical and semiconductor coatings (e.g., HfO2 high-k dielectrics).

• Ultra-Low Zirconium (Zr) Interference: Strict zirconium separation processes ensure the highest possible thermal neutron capture efficiency, which is critical for commercial and  maritime nuclear reactors.
• Refined Crystal Morphology: The iodide growth process yields a highly dense crystalline lattice with minimal interstitial gases (O, N, H), thereby enhancing secondary melting homogeneity.
• 100% Quality Traceability: Fully traceable manufacturing lot history. Testing capabilities include ICP-MS (Inductively Coupled Plasma Mass Spectrometry) for chemical assay and GDMS (Glow Discharge Mass Spectrometry) for ultra-trace impurity verification.

• Secure Vacuum Packaging: Individually wrapped in anti-oxidation vacuum-sealed plastic bags, then packed in foam-lined, export-standard wooden crates to ensure zero deformation or contamination during transit.
• Regulatory & Shipping Compliance: Handled with full safety compliance. Complete SDS/MSDS and export documentation are systematically structured (including specialized nuclear/dual-use end-user compliance documentation if required).
