Tantalum Carbide (TaC) Nanopowder / Nanoparticles (99+%, 300 nm, Cubic)

Description

Tantalum Carbide (TaC) Nanopowder / Nanoparticles (99+%, 300 nm, Cubic)

Tantalum Carbide (TaC) is an ultra-refractory ceramic compound with exceptional hardness, chemical stability, and thermal resistance. With a purity of 99+%, an average particle size of 300 nm, and a cubic crystal structure, TaC nanopowder is a premium-grade material for cutting tools, high-temperature coatings, and advanced composites.

TaC has a true density of 13.9 g/cm³ and a bulk density of 1.25 g/cm³, making it one of the densest refractory carbides. With a Mohs hardness of 9–10 (second only to diamond) and the highest known melting point of any binary stoichiometric compound (3880 °C / 4150 K), TaC is widely used in cermets, superalloys, and aerospace engineering.
