Introduction and Applications of Titanium Carbide Powder

The Structure and Properties of Titanium Carbide Powder

Titanium carbide powder is an important ceramic material with a high melting point, ultra-hard properties, chemical stability, high wear resistance, and excellent thermal conductivity. These outstanding physical and chemical properties make titanium carbide powder have broad application prospects in various fields such as mechanical processing, aerospace, and coating materials. Titanium carbide powder is widely used in cutting tools, polishing pastes, abrasives, fatigue-resistant materials, and as a reinforcement in composite materials. In particular, nano-sized titanium carbide powder has enormous market demand in abrasives, hard alloys, high-temperature corrosion-resistant coatings, and wear-resistant coatings, making it a high-value-added technological product.

Titanium carbide powder has a typical NaCl-type cubic crystal structure with a lattice parameter of 0.4327 nm. In the lattice, carbon atoms and titanium atoms are in equivalent positions. This stable lattice structure endows titanium carbide powder with excellent hardness, high-temperature resistance, and chemical stability, allowing it to maintain stable performance in various extreme environments.

Main Applications of Titanium Carbide Powder

Reinforcing Particle Materials

Metal Matrix Composite Reinforcing Particles

Titanium carbide powder can be used as reinforcing particles in aluminum, titanium, and magnesium alloys, improving the heat treatment performance, machining capability, and high-temperature resistance of the alloys. For example, in Al₂O₃-TiC composite tools, adding titanium carbide powder can significantly enhance the tool's hardness and improve its cutting performance, thereby increasing the durability and machining precision of the tool.

Ceramic Matrix Composite Reinforcing Particles

Titanium carbide powder, as reinforcing particles in ceramic matrix materials (such as oxide ceramics, boride ceramics, carbide ceramics, nitride ceramics, and glass ceramics), can effectively improve the toughness of ceramic materials and broaden their application range. For instance, ceramic tools based on titanium carbide powder have higher wear resistance and overall superior performance compared to traditional hard alloy tools, maintaining stability in more demanding machining environments.

Aerospace Materials

In the aerospace field, many key components need to operate stably in extremely high-temperature environments, such as gas rudders, engine nozzle liners, turbine rotors, blades, and structural parts in nuclear reactors. Titanium carbide powder significantly enhances the high-temperature strength of tungsten-based materials, allowing them to maintain good mechanical properties under high-temperature conditions. As the temperature increases, the reinforcing effect of titanium carbide powder on the plastic tungsten matrix becomes more pronounced, ultimately enhancing the high-temperature capabilities of the composite material and providing more reliable high-temperature material solutions for the aerospace field.

Foam Ceramic Filter Materials

Foam ceramics are efficient fluid filtration materials used to remove impurities from liquids. Their main filtration mechanisms include agitation and adsorption. To meet the needs of metal melt filtration, foam ceramic materials need to have excellent thermal shock resistance. Compared to oxide foam ceramics, foam ceramics made of titanium carbide powder have higher strength, hardness, thermal conductivity, electrical conductivity, and resistance to heat and corrosion. Consequently, they have broad application prospects in high-temperature metal melt filtration and precision casting.

With continuous breakthroughs in new materials technology, the preparation processes of titanium carbide powder are also being continuously optimized, enabling its greater role in future high-end manufacturing and emerging technology fields. The market demand for titanium carbide powder continues to grow, especially for nano-sized titanium carbide powder, which, with its high added value and superior performance, is leading the development trend of high-performance materials.
