Abstract

International audience ; 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). The BET surface area monotonically decreased which was consistent with increase in particle size. SEM photographs showed that samples exposed to Biofield after 38 days showed growth in particle size and particles joined at inter and intra particle boundaries. X-ray diffraction of the powder samples indicated both increase and decrease in crystallite size, unit cell volume, change in nuclear charge per unit volume of atom and atomic weight of samples exposed to Biofield even after 106 days.These results indicated that properties of Aluminium powders could be changed even up to atomic level by exposure to Biofield.
