Hafnium carbide powder is a kind of carbide ceramic powder with gray appearance. The chemical formula is HfC. The density is 12.7g/cm3, and the melting point is 3890 ℃. Hafnium carbide has the highest melting point among known single compounds. Hafnium carbide has high melting point, high elastic coefficient, good electric conductivity, small thermal expansion and good impact performance.

Hafnium carbide powder can be divided into coarse hafnium carbide powder, medium hafnium carbide powder, fine hafnium carbide powder, extremely fine hafnium carbide powder, ultra-fine hafnium carbide powder and hafnium carbide nanopowder according to the different particle sizes. According to different shapes, it can be divided into spherical hafnium carbide powder and irregular hafnium carbide powder.

Hafnium Carbide Powder Application

Hafnium carbide powder has high elastic coefficient, good electrical and thermal conductivity, small thermal expansion coefficient and good impact resistance. It is widely used in high-tech material technology fields such as cemented carbide, aerospace, atomic energy, electronics, coatings and hard films. It is an important basic material for thermal protection of missile guide, launch vehicle nozzle throat liner, satellite and spacecraft hood parts. Including:
1. Hafnium carbide powder can be used as a modifier for carbon carbon and carbon ceramic composite functional materials: Hafnium carbide (HfC) modified carbon fibers can significantly improve the strength of carbon fibers, increase fatigue resistance, wear resistance and high temperature resistance. The modification effect is very obvious, and all indicators are significantly improved.
2. Hafnium carbide powder can be used in cemented carbide, powder metallurgy and other fields, and can improve the strength, corrosion resistance and other properties of cemented carbide. The effect is more obvious than zirconium carbide (ZrC).
