Ammonium Dichromate

Ammonium Dichromate ((NH4)2Cr2O7) is a bright orange-red crystalline solid, readily ignited and burns producing a voluminous green residue. Acts as a strong oxidizing agent if mixed or contaminated with combustible material. Because it is flammable, we recommend a safe chemical storage building that meets specific regulations for storing Ammonium Dichromate.
