Cobalt nitrate, the molecular formula is Co(NO3)2·6H2O, which is red prismatic crystal, easily deliquescent, soluble in water and acid. Mainly used as pigments, catalysts and in the ceramic industry. Causes shortness of breath, cough, etc. after inhalation. Oral causes abdominal pain and vomiting. Inorganic oxidants that promote the fire of any incinerator in a fire.
Deliquescent in humid air, dehydration to trihydrate at 65 ° C, continue to lose a molecule of water after heating, and then decompose into cobalt oxide by heating. Can not be completely dehydrated. Contact with organic matter can cause explosion and burning.
Cobalt nitrate should be stored in a dry, clean warehouse. Keep away from fire and heat. Protect from direct sunlight. Keep the container sealed. It should be stored separately from flammable, combustible materials, reducing agents, sulfur, phosphorus, metal powders, etc. Do not mix and store. Lightly load and unload during handling to prevent damage to packaging and containers.
If a cobalt nitrate leak occurs, the leaking contaminated area should be isolated and a warning sign should be placed around it. It is recommended that emergency personnel wear gas masks and chemical protective clothing. Do not touch the spill directly. Do not allow the spill to come into contact with combustible materials (wood, paper, oil, etc.), absorb it with sand, vermiculite or other inert materials, and collect and transfer to a safe place. Such as a large number of leaks, collected or recycled or discarded after harmless treatment.
