Dense inert metal explosive (DIME) is an experimental type of explosive that has a relatively small but effective blast radius. It is manufactured by producing a homogeneous mixture of an explosive material (such as phlegmatized, HMX or RDX) and small particles of a chemically inert material such as tungsten. It is intended to limit the effective distance of the explosion, to avoid collateral damage in warfare. An emerging criticism of DIME weapons is that they might turn out to have strong biological effects in those who are hit by the micro-shrapnel from these explosives.
