Abstract
Sensitized inorganic nitrate mixtures with high brisance are provided in which oxygen balance is attained by the incorporation of aluminum dust and hydrocarbons. Cap sensitivity is achieved by adding an organic nitrate. The resultant mixtures have a low tendency to sweat and cause headaches.
Claims20
An explosive mixture consisting of an inorganic oxidizer sensitized by a liquid hydrocarbon, metallic powder and a liquid non-reducing organic nitrate;
- said liquid hydrocarbon and said liquid non-reducing nitrate being present in an amount completely absorbed by the other ingredients in order to reduce sweating by said explosive mixture.
