Description

Hafnium Bromide is an inorganic halide compound of hafnium, a transition metal known for its high corrosion resistance and neutron-absorbing properties. This material is a critical precursor in advanced materials science, particularly for the deposition of hafnium-containing thin films. It is essential for manufacturers and R&D facilities in the semiconductor, optical coating, and specialty chemical sectors seeking high-purity metalorganic sources.

Application

• Chemical Vapor Deposition (CVD) & Atomic Layer Deposition (ALD): Serves as a high-purity precursor for depositing hafnium oxide (HfO₂) and hafnium-based thin films on semiconductor wafers, crucial for high-k gate dielectrics.
• Optical & Protective Coatings: Used in the production of advanced optical coatings and wear-resistant protective layers for specialized components.
• Catalysis Research: Acts as a catalyst or catalyst precursor in specialized organic synthesis and polymerization reactions within research settings.
• Specialty Inorganic Synthesis: Employed as a starting material for synthesizing other hafnium complexes and compounds in advanced material development.
• Nuclear Industry Applications: Investigated for use in neutron absorption and control rod materials due to hafnium's high neutron capture cross-section.

Quality Control

Our Hafnium Bromide is produced and handled under stringent quality management protocols to ensure batch-to-batch consistency and high purity, suitable for demanding applications like semiconductor fabrication. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, metallic impurities, and other critical parameters. We adhere to relevant industry standards and can support requirements for traceability and documentation.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place. Due to its hygroscopic (moisture-sensitive) nature, the product should be handled under an inert atmosphere (e.g., argon or nitrogen) and kept away from moisture to prevent decomposition. Recommended long-term storage temperature is 2-8°C.
