Silver Permanganate

Silver Permanganate is an inorganic compound with the chemical formula AgMnO4. It decomposes when heated or mixed with water, and heating to high temperature may lead to explosion. The compound is used in gas masks. It has a crystal-like purplish or a grey power appearance.

"Silver Permanganate can also be called Argentous Permanganate."
