Patent ID: 8801878

Claim:
An electrically activated primer composition, comprising: metal particles having a mean size less than about 200 nanometers selected from the group of metals consisting of aluminum, magnesium, titanium, boron, silicon, and zirconium; metal-iodate particles having a mean size less than about 500 nanometers selected from the group of metal-iodates consisting of AgIO 3 , Bi(IO 3 ) 3 , Cu(IO 3 ) 2 , Zn(IO 3 ) 2 , Mn(IO 3 ) 2 , Sr(IO 3 ) 2 , Ca(IO 3 ) 2 , KIO 3 , and NaIO 3 present in approximately stoichiometric amount to react fully with said metal; and a sufficient amount of conductive material to enable ignition of the primer composition by ohmic heating.
