Application of amorphous silicon powder:
1. Nano silicon wire is made of nano silicon powder for use in the negative electrode material of rechargeable lithium battery, or graphite coated on the surface of nano silicon powder is used as negative electrode material for rechargeable lithium battery, which improves the capacity and charge of rechargeable lithium battery more than 3 times. Number of discharge cycles;
2. Nano silicon powder is used in high temperature resistant coatings and refractory materials;
3. Nano-silicon can be applied to coatings to form silicon nano-films, which are widely applied to solar energy;
4. The nano silicon powder is mixed with diamond under high pressure to form a silicon carbide---diamond composite material, which is used as a cutting tool.

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.
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.
