Abstract
Abstract A pyrotechnic cloud seeding composition comprising from about 60 to about 85 weight percent silver iodate, from about 10 to about 40 weight percent of a fuel from the class consisting of aluminium and magnesium, from about 5 to about 15 weight percent binder, and from about 0.1 to about 10 percent halogenated organic compound having a melting point of at least about 50° C. One illustrative compound is hexachlorobenzene.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
63 words
A pyrotechnic cloud seeding composition comprising a silver iodate containing oxidizing agent, a light metal fuel, a binder and an "effectiveness" improving compound selected from the group consisting of hexachlorobenzene, hexabromobenzene, pentachlorobenzene, pentabromobenzene, tetrachlorobenzene, tetrabromobenzene, hexachlorocyclohexane, hexabromocyclohexane, hexachloroethane, hexabromoethane and mixtures thereof, said compound being solid at temperatures normally encountered in the preparation and handling of the pyrotechnic composition prior to ignition thereof.
