Explosive Performance Properties of Erythritol Tetranitrate (ETN)

Erythritol tetranitrate (ETN) is a melt‐castable explosive with impressive performance, similar to the well‐known related nitrate ester, pentaerythritol tetranitrate (PETN). Though ETN has been known since 1849, its properties have not been thoroughly investigated. We report here the first 1/2′′ copper cylinder tests of ETN, compared with PETN. We discuss detonation and wall expansion velocity, along with diameter effect information in...
