Silicon (Si) Nanopowder/Nanoparticles
Purity: 97+%, Size: 25–35 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 research, enabling numerous new applications and improvements to existing technologies. Silicon nanoparticles are widely used in luminescent display devices, micro and integrated semiconductors, solar energy cells, lithium-ion batteries, silicon nanotubes, nanowires, and nanofibers. For applications requiring the highest uniformity in size and shape, we offer Si nanoparticles at the most competitive pricing.

Properties, Storage and Cautions:
Silicon nanoparticles are highly reactive and must be handled with care. Rapid movements and vibrations should be avoided. The powder should be kept away from sunlight, heating, moisture, and physical impacts. Since particle coagulation is a significant concern, 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
