Silicon (Si) Nanopowder/Nanoparticles
Purity: 97+%, Size: 35–55 nm, Oxygen Content: < 3%
Si (silicon) nanopowder is a fine yellow-brown material composed of spherical silicon particles. Its optical and electrical properties have made it increasingly valuable in recent years, enabling numerous new applications and improving existing technologies. Silicon nanoparticles are widely used in luminescent display devices, micro and integrated semiconductors, solar cells, lithium-ion batteries, silicon nanotubes, nanowires, and nanofibers. For applications requiring maximum uniformity in both size and shape, we offer Si nanoparticles at the most competitive pricing.

Properties, Storage, and Cautions:
Silicon nanoparticles are highly reactive, so they must be handled with care. Rapid movements and vibrations should be avoided. The powder must be protected from sunlight, heat, moisture, and physical impacts. Since particle coagulation is a significant issue, the material should be sealed under vacuum and stored in cool, dry conditions. Air exposure should be avoided.
Applications:
Silicon is a well-known and widely used semiconductor material. It is applied in:
-
Semiconductor and electronics industry
-
LEDs
-
Nanocomposites
-
Memory devices
