PRODUCT INTRODUCTION
description
Lead styphnate is an explosive chemical compound of lead used as a detonator. It exists in two forms of crystals and varies in color from yellow to brown. Lead is a heavy metal and stable element with the symbol Pb and the atomic number 82, existing in metallic, organic, and inorganic forms. It is mainly found in nature as the mineral galena (PbS), cerussite (PbCO3) or anglesite (PbSO4), usually in ore with zinc, silver, or copper. (L21, L415)
