Tantalum Carbide (TaC) Micron Powder (99%, 0.5–1 µm, Cubic)

Description

Tantalum Carbide (TaC) Micron Powder (99%, 0.5–1 µm, Cubic)

Tantalum Carbide (TaC) Micron Powder is a refractory ceramic material with outstanding hardness, thermal stability, and electrical conductivity. Produced with a purity of 99% and particle sizes ranging from 0.5–1 µm, TaC powder is a black-gray, odorless powder with a cubic crystal structure and a density of 13.9 g/cm³.

With an extremely high melting point of 3880 °C and a boiling point of 5500 °C, TaC is one of the most heat-resistant binary compounds known. It has a Mohs hardness equivalent of ~1800 kg/mm², excellent wear resistance, and low electrical resistivity (30 µΩ·cm), making it a vital material for ceramics, hard metals, and high-temperature engineering applications.
