Properties, Storage, and Cautions
Silicon nanoparticles are highly reactive and must be handled with care to prevent oxidation or agglomeration. Avoid rapid movements, vibrations, and impacts during handling. Store away from heat, moisture, and direct sunlight. For best preservation, the powder should be vacuum-sealed and kept in a cool, dry, and inert environment to minimize air contact and particle coagulation.
