Shelf life perchlorate

Perchlorate is the oxidation product of chlorate. It forms a variety of compounds, including ammonium perchlorate, potassium perchlorate, sodium perchlorate, and perchloric acid. Perchlorate is highly reactive in its solid state, and as ammonium perchlorate it is used as the oxidizer in solid rocket fuel. Because of its limited shelf life, it must be periodically washed out of the country s rocket and missile inventory and replaced. Large volumes of the chemical have been disposed of since the 1950s, and perchlorate has been detected in large concentrations in both groundwater and surface water. Perchlorate has also been used in the manufacture of matches, munitions, fireworks, and in analytical chemistry. 

Field experience has shown that shelf life is an outstanding characteristic of manganese dioxide-magnesium perchlorate batteries. After 18 months storage at room temperature, magnesium batteries have yielded 90% of their initial capacity. Storage for 90 days at 55 C has shown that the battery still retains 85% of its initial capacity, and after storage at THC for 30 days the capacity retention is 85%. The shelf life of...
