Nanopowders are defined as powdered materials with individual particles having sizes under 100 nanometers.
Physical Features of Nanopowders
The particles in nanopowders are smaller than the wavelength of visible light and therefore are rendered invisible. This means they can be used in applications like sunscreens that are clear. The tiny size of nanopowders gives them an extremely high surface area to volume ratio that results in extraordinary properties like extreme strength.
The applications for materials that incorporate nanopowders increase everyday. Current applications include:
• Solid Rocket Fuel
• Conducting Paste
• Magnetic tapes & fluid
• Targeted drug delivery
• Metallic paint
• Sintering aids
• Transparent polymers
• Synthetic bone
