Abstract
Abstract The invention provides inorganic oxidizer salt blasting compositions of the aqueous slurry type containing a combination of an aliphatic amine salt and a water-soluble inorganic perchlorate as a sensitizer component. Preferably, each of said amine salt and perchlorate is present in the sensitizer combination in a proportion at least stoichiometrically equivalent to that required for reaction with the other to form a corresponding amine perchlorate as at lest 3 weight percent of the composition. Often, the proportion of each ingredient of the sensitizer combination is at least 2, and generally up to 25, weight percent of the composition.
