Explosion Characteristics of Aluminum Nanopowders
Aerosol and Air Quality Research, 2010 In 2005, an investigation conducted on three nanoscale attrition millers in Taiwan revealed that all three had undergone metal nanopowder explosions in the past. This research was aimed at determining the relationships between the particle diameter of an aluminum nanopowder and its maximum explosion pressure (P(subscript max)), maximum rate of pressure
