Potassium Dichromate
chemical formula: K2Cr2O7
( granular )
Potassium Dichromate is a common inorganic chemical reagent, most commonly used as an oxidizing agent in various laboratory and industrial applications. Solutions of it are used in photography to develop negatives and in the aerospace industry to protect Magnesium metal components against corrosion. It is also used in some pyrotechnic compositions that contain Magnesium powder to prevent the decomposition of the metal.
Caution: Potassium Dichromate is both toxic & corrosive. Use normal safety precautions (wear a filter mask/respirator and gloves) when working with Potassium Dichromate. Accidental inhalation of fine particles can be dangerous.
