| Storage conditions |
1. Store in a cool, ventilated warehouse. Keep away from tinder, heat sources. It should be stored separately from oxidants and acids, and mixed storage should not be avoided. Equipped with fire fighting equipment of corresponding varieties and quantities. Storage areas should be equipped with suitable materials to contain spilled materials. |
| stability |
1. Strong corrosion resistance, oxidation is slow even at high temperature in the air. Contact with strong acids and strong oxidants should be avoided. Soluble in dilute sulfuric acid, hydrochloric acid, insoluble in water, nitric acid, aqua regia. 2. Insoluble in water, nitric acid, aqua regia, soluble in dilute sulfuric acid, hydrochloric acid. Chromium is insoluble in nitric acid, fuming nitric acid and aqua regia because they have an inactivation effect on the chromium surface. Other oxidants that can produce passivation are chlorine, bromine, and chloric acid and chromium trioxide solutions. Chromium forms a corrosion-resistant, dense oxide film in air. It emits a flash when heated with potassium chlorate, and can be combined with halogens, sulfur, nitrogen, carbon, silicon, boron and some metals under heating conditions. 3. Chromium is an inactive metal, stable to oxygen and moisture at room temperature |
