Nano titanium nitride (TiN) powder, black powder, cubic crystal type. The particle size is 20-40 nm, 100 nm. The purity is 99%+. Nano titanium nitride has high melting point, high hardness, high chemical stability and excellent electrical and thermal conductivity.

The main application of nano titanium nitride:

1. Application in PET engineering plastics: A small amount of nano titanium nitride powder can be used as a crystallization nucleating agent in thermoplastic engineering plastics such as PET, PA, etc., dispersing nano titanium nitride with ethylene glycol to prepare nano pulp It is expected that nano-titanium nitride can be better dispersed in PET engineering plastics by polymerization, which can greatly accelerate the crystallization rate of PET engineering plastics, make it simple to form, and expand the application range of PET engineering plastics. At the same time, a large number of nano-titanium nitride particles are dispersed in PET, and due to the nano effect, the wear resistance and impact resistance of PET engineering plastics can be greatly improved;

2. The application of nano-titanium nitride plastic to packaging materials with high barrier and yellowing characteristics: Nano-TiN composite material barrier technology is used to combine Nano TiN and resin to form composite materials. These nano particles can block molecular gaps and make gas Difficult to diffuse and penetrate, thus improving the barrier properties of resin and plastic. Since the amount of nanomaterials added is very small, this material can be directly applied to existing various processes without the need to update equipment. The addition ratio of 1 in 10,000 can ensure that the appearance of the polyester is transparent and clear, and the barrier performance is improved by more than 8 times. Due to the high nitrogen content of our titanium nitride, the dispersed titanium nitride slurry is light blue , Without adding any color seasoning, it can mask the yellowing characteristics of polyester itself (permanently solve yellowing), reduce the number of colorants added by customers, and reduce costs;

3. Incorporation of a small amount of titanium nitride nanopowders in tin, silver, copper, zinc and other alloys reduces the melting temperature by 200°C, produces an alloy more uniformly, and reduces the temperature of the oxide solid solution by 30°C, which can reach the original lead-tin The soldering temperature, if it can further improve the wettability, it will solve the biggest application difficulty of the existing lead-free solder;

4. Application of high thermal emissivity coating: high nitrogen content nano-TiN powder is the key material of high thermal emissivity coating material used in high temperature, and the coating material developed by adding this component is a coating prepared by plasma spraying technology , The test found that the thermal emissivity performance has been greatly improved, the product is mainly used in high-temperature furnace energy saving, military and other aspects;

5. The preparation of green electronic materials cannot use harmful elements such as lead, cadmium, and high-valent chromium. The high temperature bonding glass phase is lead-free, cadmium ceramic medium, and encapsulating glass glaze. The difficulties are high solid phase synthesis temperature, high softening point, and porcelain forming temperature. High, if you can add a small amount of titanium nitride nano-powder can reduce the solid-phase reaction temperature by 200 ℃, even if it is reduced by 50 ℃, the use of the original process equipment is also a big breakthrough. Titanium oxide and its solid solutions are themselves components of electronic materials, and the introduction of nanoforms may bring mutations with beneficial properties;
6. The pollution law restricts the use of polymers containing bromine (Br) and benzene, which poses problems for electronic flame retardant and plastic shells. If trace amounts of silicon nitride, silicon carbide, and titanium nitride are added to engineering plastics, Nano powders such as titanium carbide not only increase mechanical strength, wear resistance, heat resistance and other properties, such as the performance of flame retardant materials that can replace bromine elements, but also a great breakthrough in the application of organic polymers;
7. Applications in other fields: in nano-composite hard tools, hard alloys, high-temperature ceramic conductive materials, heat-resistant and wear-resistant materials, dispersion-strengthened materials, etc., it can also be used in fuel cell electrode catalysts, antistatic materials and conductive ceramics in.
