Application: Titanium carbide powder is used in high-temperature resistant spray coating materials, welding materials, hard film materials, military aviation materials, hard alloys, and metal ceramics. As an additive used in the production of thermistors to improve resistance. 
Synthesis method: 
Carbon thermal reduction method: 
The mixture of titanium powder obtained by reducing TiO2 with hydrogen and carbon is reacted at high temperature, or the mixture of TiO2 and carbon powder is compressed into blocks, then heated to 2300-2700 ℃ in an electric furnace and carbonized in H2 or CO atmosphere. Usage: Used for making hard alloys, as well as electrodes and abrasives for arc lamps. Reduce TiO2 with carbon black at a reaction temperature range of 1700-2100 ℃, with the chemical reaction formula: TiO2 (s)+3C (s)=TiC (S)+2CO (g).    
Direct carbonization method: 
Generate TiC by reacting Ti powder and carbon powder. The chemical reaction formula is: Ti (s)+C (s)=TiC. Due to the difficulty in preparing submicron sized metal Ti powder, the application of this method is limited. The above reaction takes 5-20 hours to complete, and the reaction process is difficult to control. The reactants agglomerate severely, requiring further grinding processing to prepare fine TiC powder particles. To obtain a purer product, it is necessary to purify the fine powder after ball milling using chemical methods. 
Purpose: 
The use of titanium carbide 
1. Application of nano titanium carbide in aerospace components 
It has a melting point of over 3000 ℃, excellent high-temperature strength, good compatibility with tungsten, similar thermal expansion coefficient, and much lower density than tungsten. 
2. Nano titanium carbide foam ceramics 
As a filter, foam ceramic can effectively remove inclusions in various fluids, and its filtering mechanism is agitation and adsorption. Filters require chemical stability of materials, especially those used in the metallurgical industry that require high melting points. Therefore, most of these materials are oxides, and in order to adapt to the filtration of metal melts, the main goal is to improve their thermal shock resistance. Nano titanium carbide foam ceramics have higher strength, hardness, heat conduction, conductivity, heat resistance and corrosion resistance than oxide foam ceramics; 
3. Widely used in the manufacturing of wear-resistant materials, cutting tools, molds, melting metal crucibles and many other fields, transparent titanium carbide ceramics are also good optical materials; Titanium carbide abrasive in the abrasive and grinding tool industry is an ideal material to replace traditional grinding materials such as alumina, silicon carbide, boron carbide, and chromium oxide; The grinding ability of nano titanium carbide is comparable to that of synthetic diamond, greatly reducing costs. Currently, it has been widely used in countries such as the United States, Japan, and Russia. Abrasives, grinding wheels, and grinding pastes made of nano titanium carbide materials can greatly improve grinding efficiency, precision, and surface smoothness. 
4. Powder metallurgy field 
Nano titanium carbide powder is used as a raw material for powder metallurgy production of ceramic and hard alloy parts, such as wire drawing dies, hard alloy molds, etc.
