Product Features
Nano silicon nitride（Si3N4)Using aerosol ablation methodPreparationHigh purity, small particle size, uniform distribution, large specific surface area, high surface activity, low bulk density, and ultraviolet reflectance ofOver 95%, and the absorption rate in the infrared band exceeds 97%. The device has a low ceramic-forming temperature, good dimensional stability, high mechanical strength, excellent chemical corrosion resistance, particularly high strength at elevated temperatures, and self-lubricating properties. It forms a fine dispersed phase in composite materials, thereby significantly enhancing their overall performance. The product itself possesses self-lubricating properties and can be used in lubricating oils. Silicon nitride, with its high hardness and low sliding friction coefficient, can be applied in metal surface ceramic wear-resistant composite plating. When used in coatings, it provides wear resistance and solvent resistance. High-purity silicon nitride can also be used as a release agent for quartz crucibles.
Product Applications
1. Manufacturing structural components: such as balls and rollers for rolling bearings, sliding bearings, sleeves, valves, and structural components with requirements for wear resistance, high-temperature resistance, and corrosion resistance used in industries like metallurgy, chemical engineering, machinery, aviation, aerospace, and energy.
2. Surface treatment of metals and other materials: such as alloys for molds, cutting tools, turbine blades, turbine rotors, and cylinder inner wall coatings.
3 Composite materials: such as metal, ceramic, and graphite-based composites; rubber, plastics, coatings, adhesives, and other polymer-based composite materials.
4 Wear-resistant self-lubricating nanoparticle film, used for surface protection of mobile phones, high-end automobiles, etc., as well as wear-resistant coatings and electrophoretic paint additives, providing high wear resistance.
Packaging and Storage
This product is filled with inert gas.Plastic bagPackaging: Store sealed in a dry, cool environment. Avoid exposure to air to prevent moisture-induced oxidative agglomeration, which may affect dispersion performance and usability. Packaging quantities can be customized according to customer requirements, with sub-packaging available.
