See Lines With Other Classes and Within This Class in the class definition.
(1) Note. Designation of an ingredient or composition as granular or particulate is not considered as defining a particular shape or structure for this and indented subclasses. See Glossary under the class definition.
(2) Note. A particular shape for this and indented subclasses is, for example, globular, needle, spherical, rectangular, sheet, cast body, pellet, etc. A physical characteristic is stating the particle size of an ingredient or the density of a composite.

The oxidant is emulsified in the fuel in the presence of the emulsifier, and a polymerizing reaction is effected after the emulsification to bind the molecules...     
4619721 Emulsion-containing explosive compositions Oct-28-1986
In emulsion blend explosives, the replacement of coarse salt particles, e.g., prills, by fines, i.e., particles which pass a No. 50 U.S. sieve, increases the water resistance of the explosive without deleteriously affecting its shelf life provided that the explosive, prior to such replacement, is storage-stable...     
4637848 High density gel explosive Jan-20-1987
High density water gel explosives having relatively large amounts of low density sensitizers are prepared by evenly dispersing a densifying material therethrough. Separation of the densifying material during the mixing and packaging of the water gel explosive is prevented by adding from about 0.1 to...     
4664728 Explosive systems May-12-1987
Water-based explosives that use siliceous boron-containing microspheres as sensitizing agents are stabilized by adding multivalent metal ions to the explosives. Zinc salts are especially useful.
4664729 Water-in-oil explosive emulsion composition May-12-1987
Provided is a water-in-oil explosive emulsion composition having a 1/2 cartridge gap sensitivity of at least about three inches, yet a water content of at least about 10 percent by weight. The composition comprises an emulsion matrix of a hydrocarbon or carbonaceous fuel component, at least one inorganic...     
4675059 Non-toxic, non-corrosive priming mix Jun-23-1987
This invention relates to priming compositions for ammunitions containing manganese dioxide as oxidizer agent in the primer mix, and to the rimfire cartridge containing dinol, manganese dioxide, tetrazene and glass.
4676849 Gas bubble-sensitized explosive compositions Jun-30-1987
This invention relates to the preparation of gas bubble-sensitized explosive compositions which are liquid during their manufacture. It is possible to achieve particularly fine bubble sizes and therefore enhanced explosive power by incorporating in the liquid composition a gas bubble-generating agent...
