FAQ

What is Nickel(II) hydroxide (CAS: 12054-48-7)?

Nickel(II) hydroxide, also known as basic nickel carbonate or nickelous hydroxide, is a chemical compound with the chemical formula Ni(OH)2. It is a white, crystalline solid that is slightly soluble in water and exhibits basic properties due to the presence of hydroxide ions.

What are the main uses of Nickel(II) hydroxide (CAS: 12054-48-7)?

Nickel(II) hydroxide is primarily used in the production of nickel-cadmium and nickel-metal hydride rechargeable batteries. It is also utilized in coatings, pigments, and as a raw material for other nickel compounds. Additionally, it is employed in the development of certain catalysts and as an absorbent in some industrial processes.

Is Nickel(II) hydroxide (CAS: 12054-48-7) safe?

Nickel(II) hydroxide can be toxic if inhaled or ingested, and prolonged skin contact can cause irritation. It is classified as a skin sensitiser and a respiratory sensitiser. Proper handling precautions include wearing gloves, goggles, and a respirator. It should be stored in a well-ventilated area and handled in a fume hood. Disposal should comply with local regulations to avoid environmental contamination.

How should Nickel(II) hydroxide (CAS: 12054-48-7) be stored?

Nickel(II) hydroxide should be stored in a cool, dry place away from direct sunlight and heat sources. It should be kept in a tightly sealed container to prevent moisture absorption and degradation. Handle with care to avoid spills and ensure proper ventilation during storage and use. Adequate fire-fighting equipment should be available in the storage area in case of emergencies.
