A non-agglomerated submicron-sized titanium carbide powder has been synthesised in a simple combustion process with titanium tetrachloride and hexachloroethane as reactants, and with magnesium as a reducing agent. X-ray analysis of the purified product revealed that only the cubic titanium carbide phase is present. High-resolution transmission electron microscopy showed that TiC particles are coated with low-ordered carbon film on the surface. To remove free carbon, a melting process with calcium metal was used.
► A simple method for producing unagglomerated and submicron-sized TiC powder is described. ► Free carbon impurities react with molten calcium producing the calcium carbide (CaC2). ► The melting process with calcium can be applied to remove free carbon from other industrially produced carbides.
