This silicon (Si) nanopowder from Nanografi is a fine, brownish yellow powder with a purity of 97+%, an average particle size of 100 nm and an oxygen content below 3%. It has a cubic crystal structure, a specific surface area above 70 m2/g and a bulk density of 0.08 g/cm3 (CAS No 7440-21-3).
At the nanoscale, silicon shows optical and electrical behaviour that differs from bulk silicon, which makes these particles a useful material for nanotechnology research and industrial development. They support work on miniaturized electronic devices, energy storage systems and optoelectronic components.
The powder is offered in 25gr, 100gr, 500gr and 1000gr packs.
- Microelectronics and integrated circuit research, where compatibility with silicon-based technology is required.
- High-capacity anode material for lithium-ion batteries.
- Solar energy cells aimed at improved conversion efficiency.
- Luminescent display devices and light-emitting diodes.
- Building blocks for silicon nanotubes, nanowires and nanofibers, and fillers in nanocomposites for better mechanical and electrical performance.
