Torpex<br />

Castable mixtures of RDX (Hexogen), TNT, and aluminum powder, e.g.<br />

a 41:41:18 mixture. It contains 1% added wax. Other phlegmatized<br />

mixtures of similar compositions are W DBX and W HBX.<br />

Leuchtspur; compositions lumineuses<br />

Tracers are slowly burning pyrotechnical compositions, used in tracer<br />

bullets, signalling cartridges, tracer rockets, and light-track shells. The<br />

colored flame is due to the presence of added salts such as sodium,<br />

barium, strontium, and copper salts. The signalling formulations also
