Description
Hafnium Diboride (HfB₂) Nanopowder
Purity: 99.5% | Average Particle Size (APS): 50 nm | Crystal Structure: Hexagonal
Product Overview
Hafnium Diboride (HfB₂) is an ultra-high-temperature ceramic material (UHTC) known for its exceptionally high melting point (~3250 °C), electrical conductivity, and oxidation resistance. As a refractory ceramic with metallic luster, HfB₂ retains strength and stability in extreme conditions, making it ideal for aerospace applications, especially in hypersonic flight systems such as nose cones and thermal protection systems.
Nano-scale HfB₂ particles offer an increased surface area and improved reactivity, enhancing their performance in composite ceramics, anti-oxidation coatings, and high-temperature electronic applications.
