It is an ideal material for electronic semiconductors and optoelectronic devices with high frequency, high power, low energy consumption, high temperature resistance and radiation resistance.

The main uses and fields of nano-scale silicon carbide:
1. Modified high-strength nylon material: nano-SiC powder has good compatibility, good dispersibility and good matrix binding in polymer composite materials, and the tensile strength of modified high-strength nylon alloy is more than 150% higher than ordinary PA6 , The wear resistance is improved by more than 3 times. Mainly used in polymer parts of armored tracked vehicles, automobile steering parts, textile machinery, mining machinery linings, train parts, etc. Densification can be achieved by sintering at a lower temperature.

2. Modified polyetheretherketone (PEEK, special engineering plastics): the surface-treated nano-silicon carbide of Jinmeng New Materials Co., when the addition amount is about 5%, it can greatly improve the wear resistance of PEEK (improve the original 30% or more).

3. Application in the rubber industry: Add about 2% gold-meng nano-silicon carbide, do not change the original rubber formula for modification, do not reduce the original performance and quality, and can increase the wear resistance by 20% -40%. Nano silicon carbide is also widely used in rubber rubber rollers, printer fixing films and other fields.

4. Surface treatment of metals and other materials: cutting tools, molds, heat-resistant coatings, heat-dissipating surface coatings, anti-corrosion coatings and wave-absorbing coatings. The nano-scale mixed particles are used to form a high-density, strong binding electrodeposition composite coating on the metal surface. The micro-hardness of the composite coating is greatly improved, the wear resistance is increased by 2-3 times, the service life is increased by 3-5 times, the bonding force between the coating and the substrate is increased by 40%, the coverage is strong, the coating is uniform, smooth and detailed.

5. Manufacturing structural devices: such as sliding bearings, liquid fuel nozzles, crucibles, high-power high-frequency molds, semiconductor components, etc. used in metallurgy, chemical, machinery, aerospace and energy industries.

6. Composite materials: Preparation of metal-based, ceramic-based, polymer-based composite materials.
