Description of key information

Based on the manufacturing conditions in which only Chromium trioxide, an organic reducing agent, water and nitric acid are used, the substance produced will only contain chromium, nitrate, hydroxide and water. The substance is produced as a solution and it cannot be produced in the anhydrous form. Between 110 oC and 125 oC the substance reaches its maximum of water loss and nitrous oxide fumes develop, with the loss of nitrate

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
