Description

Hafnium Carbide CAS NO 12069-85-1 is an ultra-high-temperature ceramic (UHTC) compound known for its exceptional hardness and thermal stability. This material is critical for applications demanding extreme performance in high-temperature, erosive, and corrosive environments. It is primarily utilized by manufacturers in the aerospace, defense, and advanced materials sectors for components such as leading edges, rocket nozzles, and cutting tools.

Application

• Aerospace Thermal Protection Systems: Used in leading edges, nose cones, and other components for hypersonic vehicles and re-entry shields due to its high melting point and ablation resistance.
• Rocket Propulsion: A key material for manufacturing combustion chambers, throats, and nozzles in solid-fuel rocket motors.
• Protective Coatings: Applied as a thin film or coating on carbon-carbon composites and other substrates to enhance oxidation resistance at temperatures exceeding 2000°C.
• Cutting Tools & Wear Parts: Incorporated into cemented carbides and composites for high-speed machining and wear-resistant components.
• Nuclear Industry: Utilized as a neutron absorber material in control rods for nuclear reactors.
• Refractory Materials: Serves as an additive in ultra-high-temperature furnace linings and crucibles.
• Composite Reinforcement: Acts as a strengthening phase in ceramic-matrix composites (CMCs) to improve fracture toughness and thermal shock resistance.

Quality Control

Our Hafnium Carbide powders are manufactured under controlled conditions and subjected to rigorous quality testing. Key parameters such as purity, particle size distribution, oxygen content, and phase composition are verified using advanced analytical techniques. A Certificate of Analysis (COA) detailing lot-specific results is provided with each shipment to ensure traceability and compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and 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) for long-term storage to prevent oxidation and moisture absorption.
