Chemical Properties


Mica has outstanding chemical properties. Mica is a complex hydrous silicate of aluminum containing potassium, magnesium, iron, sodium fluorine and/or lithium and also traces of several other elements. It is stable and completely inert to the action of water, acids (except hydrofluoric and concentrated sulfuric), alkalis, conventional solvents, oils, and is virtually unaffected by atmospheric action.
