Titanium carbide (TiC)<\/a><\/span> is one of the most important transition metal carbides used in modern high-temperature and wear-resistant applications. With a melting point of approximately 3,100 \u00b0C, extremely high hardness (around 9\u20139.5 on the Mohs scale), high elastic modulus, good electrical conductivity, low density compared to tungsten carbide, and excellent chemical stability, titanium carbide (TiC) has become a key material in cutting tools, cermets, thermal barrier systems, protective coatings, and advanced refractory composites.<\/p>

In refractory applications in particular, titanium carbide (TiC) is often introduced as an additive phase. It significantly enhances mechanical strength, improves resistance to thermal shock, and increases corrosion resistance against molten iron and slag. These advantages make titanium carbide (TiC)-containing refractories highly attractive for steelmaking and non-ferrous metallurgy industries.<\/p>

The final properties of titanium carbide (TiC) powders<\/a><\/span>\u2014such as particle size distribution, morphology, purity level, and defect concentration\u2014are strongly influenced by the synthesis route. Therefore, understanding the available preparation methods is essential for both materials engineers and industrial producers.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Direct carburization is the classical and most established industrial route for titanium carbide (TiC) production.<\/p>

In this process, metallic titanium powder\u2014typically obtained from sodium-reduced sponge titanium\u2014or titanium hydride (TiH\u2082) powder<\/a><\/span> is mixed with carbon black. The carbon content is usually adjusted to 5\u201310% above the theoretical stoichiometric value to ensure complete conversion. The powder mixture is homogenized by dry ball milling and then compacted under pressures around 100 MPa.<\/p>

The compact is placed in a graphite crucible and heated in an induction furnace at temperatures between 1500 and 1700 \u00b0C under high-purity protective gas (dew point below \u221235 \u00b0C). Reaction time and temperature depend on particle size and reactivity. Titanium derived from TiH\u2082 is particularly reactive due to its fine structure and high surface activity, allowing near-stoichiometric titanium carbide (TiC) (20.05% carbon) to be obtained after holding at 1500 \u00b0C for approximately one hour.<\/p>

Industrial relevance:<\/strong><\/p>

This method is technically mature and suitable for large-scale production. However, it requires relatively high temperatures and substantial energy input.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Self-propagating high-temperature synthesis (SHS), also known as combustion synthesis, utilizes the highly exothermic nature of the Ti\u2013C reaction. Once locally ignited, the reaction front propagates through the reactant compact without continuous external heating.<\/p>

The adiabatic reaction temperature of Ti and C is sufficiently high to sustain rapid transformation into TiC. Compared with conventional carburization, SHS improves production efficiency by approximately 1.5 to 3 times. The method is particularly attractive for batch production of refractory compounds.<\/p>
