• The mining industry tends to use nitrate-based explosives such as emulsions of fuel oil and ammonium nitrate solutions, mixtures of ammonium nitrate prills (fertilizer pellets) and fuel oil (ANFO) and gelatinous suspensions or slurries of ammonium nitrate and combustible fuels. (wikipedia.org)
  • Later I mixed ammonium picrate with Al and AN. (sciencemadness.org)
  • Sensitive materials that can be initiated by a relatively small amount of heat or pressure are primary explosives and materials that are relatively insensitive are secondary or tertiary explosives. (wikipedia.org)
  • For further information on explosive hazards of chemicals, see the National Research Council's guide, Prudent Practices in the Laboratory: Handling and Disposal of Chemicals, pages 54-57. (umn.edu)
  • Most metal, nonmetal, and amine perchlorates can be detonated and may undergo violent reaction in contact with combustible materials. (umn.edu)
  • Gunpowder was the first form of chemical explosives and by 1161, the Chinese were using explosives for the first time in warfare. (wikipedia.org)
  • In turn, these have largely been replaced by more powerful explosives such as C-4 and PETN. (wikipedia.org)
