Properties & Handling
Tungsten nanoparticles are highly reactive and flammable. They must be handled with care, avoiding rapid movement, mechanical vibrations, or impacts. Exposure to air, moisture, heat sources, and sunlight should be strictly avoided to prevent oxidation, agglomeration, and degradation.
Storage Recommendation:
Store in a sealed vacuum or inert atmosphere.
Keep in a cool, dry, and dark environment.
Avoid mechanical stress and exposure to open air.
