Aluminum/cuprous oxide thermite

Technical Report ·
OSTI ID:5433671

Thermite is a generic name applied to a class of metal-metal oxide reactants that undergo a chemical oxidation reduction reaction with the liberation of large amounts of thermal energy. If a mixture of aluminum and cuprous oxide is ignited, the thermitic reaction 2Al + 3Cu/sub 2/O ..-->.. Al/sub 2/O/sub 3/ + 6Cu will proceed at such a rapid rate (burn rate of 6 cm/s) and with the evolution of so much heat (580 cal/g) that the temperature will rise to about 2570/sup 0/C. The thermite reaction, accordingly, has been used for sabotaging or destroying military equipment, starting military fires, and welding together large sections of metal. Aluminum/cuprous oxide (Al/Cu/sub 2/O) thermite is discussed in this report with respect to these topics: reactant powder characterization; power contaminant extraction; reactant powder compaction into a consolidated pellet; initiation system; and reaction and reaction product analysis.
