Electro-Explosive Device

A mixture of aluminium powder and hot copper oxide exploded violently during mixing with a steel shovel on an iron plate. The frictional mixing initiated the thermite-like mixture [1]. Such mixtures are now used in electro-explosive devices [2], Two cases of violent explosions after adding scrap copper to molten aluminium are discussed. In both cases, when some undissolved copper with adhering aluminium and oxide dross was removed from the furnace, the explosions occurred outside the melting furnace [3],...

This makes BNCP safer for handling and transportation and as a result, it is likely to be a potential replacement for conventional DDT explosives. Also, it is compatible with the semi-conductor bridge. As a consequence of all these favorable properties, HEMRL and ARDE, Pune are jointly developing the use of BNCP as a DDT explosive for semi-conductor bridge (SCB)-based safe electro-explosive devices (EEDs) [245, 246].

FILUP (Franklin Institute Laboratories Universal Pulser). This instrument is used for testing Electro-Explosive Devices (EED s) (See in Vol 5 of Encycl, p E63-L). It supplies constant current or constant voltage pulses of varying magnitude duration. It is also capable of measuring EED s resistance and functioning times and provides containment for the initiator being tested. The instrument is described in Ref 2 and a more recent version is described in Ref 3...
