| 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. |
| Chromium Preparation Products And Raw materials |
| Raw materials | Chromium oxide-->Aluminium silicon-->Chrome iron ore |
| Preparation Products | Chromium carbide |
