Note: We can supply different size products of amorphous silicon powder according to client's requirements.
Silicon powder is with high melting point, good heat resistance, high resistance and high resistant to oxidation, known as the "industrial MSG" which is a lot of high-tech industries indispensable basic raw materials.
Application of amorphous silicon powder:
1.Lithium battery anode material: Nano silicon wire is made of nano-Si powder used in the negative electrode material of rechargeable lithium battery, or graphite is coated on the surface of nano-silica powder to be used as negative electrode material for rechargeable lithium battery, which improves the charge of rechargeable lithium battery by more than 10 times. Capacity and number of charge and discharge cycles.
2.Nano-Silicon Semiconductor Luminescent Material: A silicon/silicon oxide nanostructure designed on a silicon substrate that enables photoluminescence and forward or reverse biasing of major wavelengths from near-ultraviolet to near-infrared (including 1.54 and 1.62 μm) Lower low threshold voltage electroluminescence.
3.Aluminum castable: Adding Si powder can significantly reduce the creep rate of high-alloy cast cast of high-temperature furnace, prevent cracking and spalling of the lining due to shrinkage and creep, and improve service life.
4.Auto Beauty Products: Increases shine and fills the surface with tiny cracks.
5.Tire cord fabric: adding nano-Si powder to the tire cord fabric can improve the 300% modulus of the vulcanizate, tensile properties, tear strength, Mooney viscosity, and a certain reinforcing effect on the rubber compound. .
6.Coating: Adding nano-Si powder to the coating system can improve the anti-aging, scrubbing and anti-staining properties of the coating and ultimately extend the service life of the coating.
SEM & XRD of amorphous silicon powder:
Storage conditions:
amorphous silicon powder should be sealed and stored in a dry and cool environment. It should not be exposed to the air for a long time, to prevent agglomeration due to moisture, affecting the dispersion performance and use effect, and should avoid heavy pressure, do not contact with oxidant, and transport according to ordinary goods.
