Definition of "roburite" [roburite]

• A trade-name for an explosive, consisting essentially of ammonium nitrate and chlordinitrobenzene, varied sometimes by the substitution or addition of other ingredients. It is claimed that this material is safer in use than many other explosives, and particularly well adapted to coal-mining and quarrying; but the deliquescent character of ammonium nitrate requires protection from contact with the air.
