Nanopowder Overview
Nanopowder refers to ultrafine particulate materials with at least one dimension in the 1–100 nm range, or composed of such particles as basic units. These powders feature extremely high specific surface area, surface activity, and nanoscale effects. They can be composed of metals, oxides, carbides, nitrides, and exhibit unique physical, chemical, and mechanical properties not found in traditional materials.

Nanopowder

Characteristics of Nanopowder:

  • Small size effect: Increased specific surface area at nanoscale enhances surface activity and chemical reactivity.
  • Surface effect: High percentage of surface atoms influences properties like catalysis and adsorption.
  • Quantum size effect: Alters optical, electrical, and magnetic properties at nanoscale due to electron behavior.

Advantages over Traditional Powders:

  • Higher reactivity and catalytic efficiency
  • Lower sintering temperatures and denser final structures
  • Ideal for super-strong materials, transparent ceramics, and coatings
