Mô tả

TiB2 is very similar to titanium carbide, an important base material for cermets, and many of its properties (e.g. hardness, thermal conductivity, electrical conductivity and oxidation resistance) are superior to those of TiC:

· Exceptional hardness (25–35 GPa Vickers at room temperature, more than three times harder than fully hardened structural steel), which is retained up to high temperature.

· High melting point (3225 °C),

· High thermal conductivity (60-120 W/(m K)),

· High electrical conductivity (~105 S/cm)

With respect to chemical stability, TiB2 is more stable in contact with pure iron than tungsten carbide or silicon nitride.

TiB2 is resistant to oxidation in air at temperatures up to 1100 °C, and to hydrochloric and hydrofluoric acids, but reacts with alkalis, nitric acid and sulfuric acid.
