Barium chlorate periodates

These two groups include chlorates, bromates, iodates, perchlorates, and periodates. Of these, only potassium chlorate and potassium F>erchlorate are of pyrotechnic importance because they are the most stable nonhygroscopic salts in this class. Barium chlorate is found in fireworks but has been abandoned for military purposes ammonium perchlorate is rarely found but is important in propellants. 

The chemistry that governs barium salts, as used in green stars, is somewhat analogous to that of the strontium salts employed in red stars since both elements are found in the same group of the periodic table. While the use of compounds such as strontium chloride, strontium chlorate or strontium perchlorate might be considered to be appropriate...
