Description

Hafnium Carbide (HfC) Nanopowder/Nanoparticles

Purity: 99.5% | Average Particle Size: 800 nm | Crystal Structure: Cubic


Product Overview

Hafnium Carbide (HfC) is a gray, ultra-high-temperature ceramic compound known for its extremely high melting point—among the highest of any binary compound (~3890 °C). This makes HfC ideal for thermal and wear-resistant applications in the most demanding environments. It exhibits remarkable hardness, electrical conductivity, and chemical stability even under extreme thermal stress.
