FAQ

What are the physical and chemical properties of Nickel fluoride tetrahydrate (CAS: 13940-83-5)?

Nickel fluoride tetrahydrate (NiF2·4H2O) is a white crystalline solid. Its molecular weight is approximately 218.68 g/mol. It is slightly soluble in water and has low solubility in ethanol. Chemically, it is relatively stable but may react with strong acids to produce hydrogen fluoride gas. It is used in various applications due to its unique properties.

How is Nickel fluoride tetrahydrate (CAS: 13940-83-5) typically synthesized?

Nickel fluoride tetrahydrate is often synthesized by reacting nickel nitrate with hydrofluoric acid and subsequently drying the product. The process typically involves controlling the reaction temperature and pH to achieve high selectivity and yield. Commonly, this method produces a product with a purity of over 98%.

What industries use Nickel fluoride tetrahydrate (CAS: 13940-83-5)?

Nickel fluoride tetrahydrate (NiF2·4H2O) is used in various industries. It is a key component in the synthesis of nickel-based catalysts for chemical reactions, particularly in the production of pharmaceuticals and polymers. It is also used in the fabrication of sensors and semiconductors due to its unique electronic properties.

What precautions should be taken when handling Nickel fluoride tetrahydrate (CAS: 13940-83-5)?

When handling Nickel fluoride tetrahydrate, appropriate personal protective equipment (PPE) such as gloves, safety glasses, and a lab coat should be worn. It should be stored in a cool, dry place away from direct sunlight and strong acids. In case of a spill, it should be handled using appropriate spill cleanup procedures and the Material Safety Data Sheet (MSDS) should be consulted for detailed guidance.
