  • This suspension comprises solid micro or nano material mixed with: liquids, gases, or vapours. While the disintegrated metal fragments form a myriad of objects ( the suspended phase ), the surrounding media forms as a "solvent ", or " carrier ". Typically, disintegration process described here lasts from a fraction to few microseconds. Such a very short time of an electrical pulse duration is paramount to the success of the process outlined herein.
  • each metallic crystal is characterized by two important technological factors: actual tensile strength ( to be determined for a certain temperature ), and needed current pulse characteristics.

Circuit characteristics comprise knowledge on circuit size, inductance, resistance, capacitance, pulse voltage, pulse current, and current/ time relationship. Once such characteristics and as well as other process parameters are known, the colloid fabrication process may be tried for the broad variety of dispersing media.

The process of explosive Micro or nano particle making is clean since it does not live waste behind. However, nano or micro particles generated under the conditions outlined herein are produced in rather broad spectrum of sizes. Centrifugal sedimentation, or filtering may be used tiierefore for narrowing the span in particle sizes.
