Properties, Storage and Cautions:
Silicon microparticles are highly reactive and must be handled carefully. Rapid movements, mechanical vibrations, and physical impacts should be avoided. The powder must be stored away from sunlight, heat sources, moisture, and any conditions that may cause oxidation or agglomeration. To maintain stability, it should be sealed under vacuum and kept in cool, dry conditions with minimal air exposure.
Applications:
Silicon is a widely used semiconductor material with applications in:
- Semiconductor and electronics industry
- LEDs
- Nano-composites
- Memory devices
