    The product has high purity, small particle size, uniform distribution, high specific surface area, high surface activity, low bulk density, 90% of ultraviolet reflectance and absorption rate of more than 97% in infrared absorption, , Good dimensional stability, high mechanical strength, good resistance to chemical corrosion, especially high temperature strength, and self-lubricating effect, which in the composite material to form a fine dispersion phase, thus greatly improving the overall performance of composite materials. The product itself has self-lubricating properties, can be used in lubricating oil. High hardness of silicon nitride, sliding friction coefficient of small features can be used in metal surface ceramic wear-resistant composite plating applications.

    The main purpose:

    Manufacture of precision structural ceramic devices: such as metallurgical, chemical, mechanical, aviation, and energy industries such as the use of rolling bearings ball and roller, sliding bearings, sets, valves and wear, high temperature, corrosion resistance requirements of the structural devices.

    Metal and other materials surface treatment: such as molds, cutting tools, turbine blade turbine rotor and cylinder wall coating.

    Preparation of high-performance composite materials such as metal, ceramic and graphite-based composites, rubber, plastics, coatings, adhesives and other polymer-based composites.

    In the application of high wear-resistant rubber: the main rubber for the EPDM rubber bellows added 1-3 copies of Si3N4 powder, durable products can be 20 million times to more than 100 million times, performance increased by 5 times.

    Metal surface wear-resistant composite plating applications: high hardness of silicon nitride, sliding friction coefficient is small, its mechanical properties compared with other ceramic materials; compared with metal materials, silicon nitride room temperature strength can be maintained above 800 , even if Between 1200 -1400 , will still maintain a considerable strength, such as harsh occasions, should be used on the surface of Si3N4 metal composite materials. 

    Absorption of infrared textile applications: silicon-based nano-powder is nylon, polyester reinforced conductive. Nano-nitride has a human absorption of infrared absorption rate of more than 97%, is the best absorption of infrared ultra-fine textile additives.

    Polysilicon and single crystal release agent applications: Polycrystalline silicon and monocrystalline silicon melting ingot for silicon melt and quartz crucible stripping between the mold to prevent melting silicon and crucible paste, and play a blocking effect to ensure that silicon products The purity.

    In LED materials: nano Si3N4 phosphors belong to the individual luminescent centers (cerium Ce3, europium Eu2) luminescent materials. The energy transition process belongs to f-d transition.

    Nano-silicon nitride in other industrial applications: high-performance wear-resistant, high temperature rubber seals and tires, anti-corrosion refractory coating applications in high temperature insulating electronic materials and inorganic ceramic lubricating oil applications can also be applied to the structure ceramics and inorganic composites.


    This product should be stored in a cool, dry room, and avoid stress. The powder without the treatment of surface should not be exposed to the air during the use, to aviod absorb moisture agglomeration, affect the dispersion performance and the use of results.
