1. What is Nano Silicon Powder?

Nano Silicon Powder consists of elemental silicon particles with dimensions in the nanometer range. Reducing silicon to nanoscale dimensions can significantly increase surface area and alter its electrochemical, electrical, and material properties.

2. What is Nano Silicon used for?

Nano silicon is widely researched for lithium-ion battery anodes, semiconductor materials, photovoltaics, conductive composites, sensors, energy storage, and nanotechnology applications.

3. What particle sizes are available?

REG Metals can source silicon nanopowders with customized particle sizes, including approximately 20–100 nm ranges, as well as other nanoscale distributions depending on the manufacturing process.

4. Is Nano Silicon spherical or irregular?

Both spherical and irregular silicon nanoparticles can be sourced. Morphology should be specified when it is important to the application because it can affect surface area, packing behavior, conductivity, and electrochemical performance.

5. Can Nano Silicon be supplied with a controlled oxygen content?

Yes. Oxygen content and surface oxidation can be controlled or specified depending on the manufacturing process and intended application. Surface oxide levels should be included in the purchasing specification when critical.

6. Does REG Metals provide a Certificate of Analysis?

Yes. A Certificate of Analysis (COA) can be supplied documenting silicon purity, particle size, particle-size distribution, morphology, crystallinity, oxygen content, specific surface area, and other applicable specifications.
