Hafnium Diboride (HfB2) Nanopowder/Nanoparticles

Purity: 99.5 %, Size: 50 nm

Hafnium Diboride (HfB2) Nanopowder is an ultra-high temperature ceramic (UHTC) material characterized by an extraordinary combination of a high melting point, superior thermal conductivity, and metallic-level electrical conductivity. Produced via high-frequency plasma gas-phase synthesis (CVD), this nano-scale powder exhibits a hexagonal crystal structure with a distinct metallic luster. Its chemical profile is exceptionally stable, demonstrating near-total inertness to most chemical reagents at room temperature. The material is distinguished by its ability to maintain structural integrity and resist oxidation under extreme thermal loads, making it a foundational component for materials exposed to hypersonic flow and harsh atmospheric re-entry conditions. Its high-surface-area nanocrystalline form allows for enhanced sintering activity, enabling the fabrication of dense composite architectures that require a precise balance of mechanical toughness and thermal shock resistance.

Technical Properties

Applications

• Hypersonic Aerospace Components: Used in the fabrication of leading edges and nose cones for high-speed aircraft and re-entry vehicles where temperatures exceed the limits of conventional materials.
• Thermal Protection Systems (TPS): Key constituent in anti-oxidation composite materials and specialized coatings designed for extreme-environment aerospace structures.
• Nuclear Engineering: Acts as an efficient neutron absorber in control rods and shielding applications due to the high neutron capture cross-section of hafnium.
• Refractory & Chemical Equipment: Utilized for crucible linings and corrosion-resistant hardware that must withstand the aggressive nature of molten metals and chemical vapors.
• Advanced Wear-Resistant Coatings: Applied as a hard, high-temperature coating to improve the longevity and performance of industrial tools and machinery operating under intense friction.
• Composite Ceramics: Serves as a primary additive in the production of ultra-high temperature ceramic matrix composites (CMCs), enhancing overall thermal and oxidative stability.
• Energy Applications: Integrated into heat-enhancing additives and specialized electronic components that require stable conductivity at high operating temperatures.
