Metal-based powders are high-density energy carriers. Their behavior can be classified by FOUR properties:<\/p>

  1. Composition<\/li>
  2. Size<\/li>
  3. Shape<\/li>
  4. Finishing<\/li><\/ol>

    Reactivity of powders can be modified, controlled, and tailored by altering these properties.\u00a0<\/p>

    Typically, composition and reaction thermodynamics define the ideal energy content of the composition.<\/p>

    Physical and chemical features master the rate at which the reaction takes place.\u00a0\u00a0<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

    With this process, powders are treated to change one or more physiochemical properties, modifying their reactivity.<\/p>

    A typical method of mechanical activation is called ball milling. It consists of processing the powder with a set of metal spheres and, possibly, with other additives and processing agents.<\/p>

    This process can generate powders with higher reactivity, tailored by the processing energy and the additives.<\/p>
