Nickel(II) carbonate basic hydrate is an organometallic compound with the appearance of green powder. Its CAS number is 12607-70-4, EINECS number is 235-715-9, chemical formula is NiCO₃・2Ni (OH)₂, and molecular weight is 304.12. Its boiling point is 333.6℃ at a pressure of 760 mmHg. It is stored at room temperature and has the characteristic of being hygroscopic. It appears as green crystals or crystalline powder. It is insoluble in water, soluble in ammonia water and dilute acid, and decomposes into nickel oxide and carbon dioxide when heated above 300℃.
Nickel(II) carbonate basic hydrate
Nickel(II) carbonate basic hydrate is generally considered to be toxic and may cause various hazards to the human body. For example, inhalation may cause respiratory irritation and lung damage, and long-term contact may cause sensitization and carcinogenesis. Appropriate protective clothing and gloves should be worn when using it.It should be stored in a cool and ventilated warehouse. Keep away from fire and heat sources and avoid direct sunlight. The package should be sealed and protected from moisture and rain. It should be stored separately from oxidants, acids, etc., and should not be mixed. The storage area should be equipped with appropriate materials to contain leaks.
Nickel(II) carbonate basic hydrate has many uses:
- Battery materials: It can be used as a raw material for preparing battery electrode materials such as nickel-hydrogen batteries and nickel-cadmium batteries, which helps to improve the performance and stability of batteries.
- Catalyst: It can be used as a catalyst or a carrier of a catalyst in some chemical reactions to promote the reaction, such as playing a catalytic role in some organic synthesis reactions.
- Ceramic and glass industry: Adding it to ceramic and glass products can improve their performance, such as increasing color, hardness and heat resistance.
- Electroplating industry: It is used for electroplating nickel to form a corrosion-resistant and wear-resistant nickel coating on the metal surface, improving the quality and service life of metal products.
