Metal powders

Metal-based powders are high-density energy carriers. Their behavior can be classified by FOUR properties:

  1. Composition
  2. Size
  3. Shape
  4. Finishing

Reactivity of powders can be modified, controlled, and tailored by altering these properties. 

Typically, composition and reaction thermodynamics define the ideal energy content of the composition.

Physical and chemical features master the rate at which the reaction takes place.

Mechanical activation

Powder activation

With this process, powders are treated to change one or more physiochemical properties, modifying their reactivity.

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.

This process can generate powders with higher reactivity, tailored by the processing energy and the additives.

Featured research activities

Hydrolytic propulsion

Using water and activated aluminum powder to generate propulsion, on demand, without power sources.
This activity is financed by the project MUSA

Thermite for Demise (T4D)

The use of thermites (in different shapes) to support the decommissioning of satellites during their atmospheric reentry is under investigation. Thermite activation can tune the ignition temperature.
