Aluminium powders are used in a wide range from propelling rockets to improving personal hygiene. More popular industrial applications include manufacture of silver metallic pigments, paints, inks, plastics, packaging, textiles and aerospace industry. As thick film pastes used in the manufacture of silicon solar cells, and as reducing agent and sources of heat, used in alumina thermic and exothermic applications. In the present investigation, Aluminium powders were exposed to non-contact Biofield treatment. Both the exposed and unexposed powders were later characterized by various techniques. The average particle size, after a slight initial decrease was found to increase after 80 days of treatment substantially, which suggested the operation of competing mechanisms fracture and sintering (micro welding).
