Show A How Explosive. MFJMm While aluminum has been employed Wfmmm to produce Intense heat for welding and-- lH similar purposes for some years, It Is . Hl only recently that If Is found as an in- H crrcdlcnt of an explosive where this ac- H tlon Is also required. In -"ammonal," a IH new explosive invented by an Austrian jH named Fuhrer, powdered aluminum Is H combined with carbon and ammonium IH nitrate. Aluminum has a high affinity H for oxygen, and when these elements H unite intense heat Is generated, which, BB In the case of tho explosive, raises the B temperature of the gas2s produced by tho decomposition of ammonium nl- HNB Irate. Increasing the temperature la IH equivalent to increasing the explosive H effect, and preliminary results indicate IIH the high power of this new explosive. IH If the addition of aluminum to an ex- iHH plosive compound has the beneficial re- Hl suit claimed In this Instance, there is RHI no reason why it should not find wider HB I application.
