Silicon Carbide SIC Nanoparticles

• Silicon carbide nanoparticles possesses high purity, narrow range particle size distribution, and larger specific surface area
• Silicon carbide nano powder has chemical stability, high thermal conductivity, smaller thermal expansion coefficient and better abrasion resistance
• The micro hardness of SiC nanoparticles is 2840 ~ 3320kg/mm2 and hardness is between corundum and diamond; Its mechanical strength is higher than the corundum;

1. High-grade refractory material;

Silicon carbide nanopowder is specially used material for polishing abrasive; Ceramic bearings; Ceramic engine parts; Grinding wheels; Textile ceramics; High-frequency ceramics; Hard disc and a support for multichip modules; High-temperature and high-power semiconductors; High-temperature ceramic bearings; High-temperature fluid transport parts; High hardness grinding materials; High-temperature sealing valves; High-temperature spray nozzles; Integrated circuit substrate; Catalyst support; Mirror or coatings for extreme ultraviolet environment; Nanocomposites (e.g., Si3N4/SiC, SiC/polymer); Resistance heating elements; Strengthening materials for Al, Al2O3, Mg, and Ni…..

2. Used as a new material to modify high-strength nylon alloys

Nano SIC powder has good dispersion and compatibility in polymer composites. The high-strength nylon alloy has a better tensile strength which is 10% higher than the ordinary PA6, and the wearing resistance increased by more than 2.5 times. Silicon carbide nanopowder is mainly used for producing armored tracked vehicles polymer parts, steering parts, textile machinery, mining machinery, linings, trainparts which can achieve densification at a lower temperature sintering.

3. Used to modify the wearing resistance of special engineering plastics, polyether ether ketone (PEEK)

After surface treatment with coupling agent, nano silicon carbide can greatly improve and enhance the wear resistanceof PEEK with the dosage of about 10%, (The abrasion of PEEK filled with micron silicon carbide is mainly pear cut and abrasive wear, The abrasion of PEEK filled with nano scale silicon carbide is mainly slight wear with adhesive transfer wear )

4. Nano silicon carbide in the rubber tire

Add a certain amount of nano silicon carbide does not change the original glue formula modification, without compromising its original performance and quality under the premise of the wear resistance can be increased by 15% -30%. In addition, the 20-nanometer silicon carbide used in the rubber roller, printer fuser film wear, heat, temperature and other rubber products. Nano SiC composite nickel and other metal surfaces: nanoscale particles of mixed particles, nickel matrix metal, the metal surface to form a high density,binding very good electrodeposited composite coating, the metal surface withsuper-hard (wear) and antifriction (lubricating) high-temperature characteristics.The microhardness of the composite coating greatly improve the wear resistance is increased by 3-5 times, 2-4 times the service life of the coating and substrate binding by 30-40%, coverage ability, uniform coating, smooth, detailed. Other applications: high-performance structural ceramics (such as rocket nozzles, nuclear industry, etc.), the absorbing material, anti-wear grease, high-performance brake pads, high hardness and wear-resistant powder coating,ceramic composite enhanced toughening.

Damp reunion will affect its dispersion performance and using effects, therefore, this product should be sealed in vacuum and stored in cool and dry room and it should not be exposure to air. In addition, the product should be avoided under stress.
