Description

Hafnium Boride (CAS NO 12007-23-7) is an advanced refractory ceramic material prized for its exceptional thermal stability, high hardness, and excellent chemical resistance. This compound is critical for high-performance applications where extreme temperatures and corrosive environments are a challenge. It is primarily sought by manufacturers in the aerospace, defense, and advanced materials sectors for producing ultra-high-temperature ceramics (UHTCs), wear-resistant coatings, and specialized components.

Application

• Ultra-High-Temperature Ceramics (UHTCs): A key component in composites for leading edges of hypersonic vehicles, rocket nozzles, and thermal protection systems.
• Wear-Resistant Coatings: Used to create hard, durable coatings on cutting tools, turbine blades, and mechanical seals to extend service life.
• Neutron Absorption: Utilized in control rods and shielding within nuclear reactors due to hafnium's high neutron capture cross-section.
• Electrically Conductive Ceramics: Serves in applications requiring materials that combine electrical conductivity with refractory properties, such as electrodes and heating elements.
• Reinforcement Phase: Acts as a strengthening additive in metal matrix composites (MMCs) to enhance hardness and high-temperature performance.
• Thin Film Deposition: Employed as a sputtering target for depositing thin films in semiconductor and optical coating processes.

Quality Control

Our Hafnium Boride is manufactured under controlled conditions to ensure batch-to-batch consistency and high purity. Quality is verified through a suite of analytical techniques including X-ray diffraction (XRD) for phase identification, inductively coupled plasma (ICP) analysis for metallic impurities, and laser diffraction for particle size distribution. A Certificate of Analysis (COA) detailing purity, particle size, and other critical parameters is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be kept under an inert atmosphere (e.g., argon or nitrogen) for long-term storage to prevent surface oxidation. Keep away from strong acids and strong oxidizing agents.
