Chromium Usage And Synthesis
Chemical Properties very hard silvery grey metal
General Description Very hard gray solid with a metallic luster.
Air & Water Reactions May be pyrophoric, as dust. Insoluble in water.
Reactivity Profile Chromium reacts violently with NH4NO3, N2O2, Li, NO, KClO3, SO2 . Metal dusts when suspended in atmospheres of carbon dioxide may ignite and explode.
Fire Hazard Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated.
