Diborides and carbides of zirconium, hafnium, and tantalum (ZrB2, ZrC, HfB2, HfC, TaC, etc., melting points well above 3200 K), are referred as ultra-high-temperature-ceramics (UHTCs) and are considered the best-emerging materials for applications in aerospace and advanced energy [Read More]

Hafnium carbide (HfC) has been intensively investigated in recent years for its great potential in ultra-high temperature appli- cations, due to its high melting point (about 3900 ◦C), phase stability, as well as good thermomechanical and thermochemi- cal [Read More]

Industrial TiC powders were originally prepared by reducing TiO2 with carbon black. The reaction temperature ranged from 1700 to 2100°C. The reaction equation was as follows: TiO2(s) +3C(s) = TiC(s) + 2CO(g) Because the reactants exist as dispersed [Read More]

Titanium carbide has a high melting point, high bowl height, and good chemical stability. It is mainly used to make cermets, heat-resistant alloys and hard alloys. The composite materials prepared with titanium carbide have a wide range of [Read More]
