Performance characteristics:

This product has high purity, small particle size, uniform distribution, large specific surface area, high surface activity, and low bulk density. The product is non-toxic, tasteless, and other characteristics. Nano silicon powder is a new generation of optoelectronic semiconductor materials with wide gap energy semiconductors, and is also a high-power light source material.

The main purpose:

Lithium battery anode material: use nano Si powder to make nano silicon wire and use it in the negative electrode material of rechargeable lithium battery, or use graphite on the surface of nano silicon powder as the negative electrode material of rechargeable lithium battery, which increases the power of rechargeable lithium battery by more than 10 times. Capacity and number of charge and discharge cycles.

Nano-silicon semiconductor light-emitting materials: silicon/silicon oxide nanostructures designed on silicon substrates can realize photoluminescence and forward or reverse bias in the main wavelength bands (including 1.54 and 1.62 μm) from near ultraviolet to near infrared Under low threshold voltage electroluminescence.

Aluminum castable: The addition of Si powder can significantly reduce the creep rate of high-aluminum castables for high-temperature furnaces, prevent the lining from cracking and peeling due to shrinkage and creep, and increase the service life.

Car beauty products:increase luster and fill up micro cracks on the surface.

Tire cord rubber compound: Adding nano-Si powder to the tire cord rubber compound can increase the 300% tensile stress, tensile properties, tear strength, and reduce Mooney viscosity of the vulcanized rubber, which has a certain reinforcing effect on the rubber compound. .

Coating: Adding nano-Si powder to the coating system can improve the anti-aging, scrubbing resistance and stain resistance of the coating, and ultimately extend the service life of the coating.

Precautions:

This product should be stored in a cool, dry room to avoid heavy pressure. The powder without surface treatment should not be exposed to the air during use to avoid moisture absorption and agglomeration, which will affect the dispersion performance and use effect.
