a) Electro exploded metal nanopowders are ultrafine particles of aluminum and other metals. The chemical reactivity of a material is related to its surface area, and the smaller particles material are, the greater the material's surface area per volume is (particles with 1/10th the diameter will have 100 times as much surface area per volume of material).
b) Electro-exploded Nanopowders are from 5 to 500 times smaller that the smallest previously commercially available metal powders, so their surface area per volume- and reactivity- is immensely greater.
c) Relatively small (compared to other physical methods) size distribution of particles.
d) Relative stability of nanopowder properties under normal conditions and high activity in various chemical processes.
e) Low temperature of nanoparticle agglomeration.

- Reactive Electro-Exploded Nano Powders Physical Properties Available:
a) Usually 50 to 100 nanometers
b) Micron/ nanometer sizing can possibly be produced to customer specification
The wire exploded nano powders will have uses in electronics, optics, processing industry, high-energy materials, chemical industry, materials science, radio-absorbing coatings, electronic engineering, aerospace, medicine, pharmaceutics, cosmetology. improved lubricants, catalysts and wear and corrosion resistant coatings, as well as enhancing combustion for rocket fuels.
a) Most metals are stocked in 100 g. (dry weight basis) containers.
b) The powders that are readily combustible are shipped dry under argon. The more reactive or pyrophoric ones are submerged under oil to form thick slurries where the metal content is about 20-30% by volume.
c) We believe that with the exception of the precious metals, most of the powders would either be pyrophoric or readily contaminated when exposed to air.

Varies according to chemistry
a) Before using reactive electro exploded (EEW) nanopowders, the user shall determine the suitability of the product for its intended use, and user assumes all risk and liability whatsoever in connection therewith.
b) Please visit and read this excellent "Approaches To Safe Nanotechnology" document from the CDC & NIOSH
c) With the publication of the "Approaches to Safe Nanotechnology" document, NIOSH hopes to: raise awareness of the occupational safety and health issues involved with nanotechnology; make recommendations on occupational safety and health best practices in the production and use of nanomaterials; facilitate dialogue between NIOSH and its external partners in industry, labor and academia; respond to requests for authoritative safety and health guidelines; and, identify information gaps and areas for future study and research.
