General description

Nickel(II) chloride (NiCl2) is a nickel based halide that is prepared by burning nickel in chlorine. It is a water soluble compound that crystallizes to form a hexahydrate. It is majorly utilized in organic synthesis as a catalyst and a precursor.

Application

NiCl2 can be used in the form of a nanoparticle for the development of separation membranes for the wastewater treatment. It can also be used to form an electron with sodium ions for the fabrication of sodium nickel chloride based batteries.

Features and Benefits

The vapor-phase co-reductions with other metal halides such as aluminum chloride (cat. no. 449598) by hydrogen results in finely divided intermetallics with applications as structural materials or compounds with useful thermoelectric, magnetic, and oxidation-resistance properties. Used in the synthesis of semiconducting metal-containing polymers in which the polypyrrole backbone has a conformational energy minimum and is nearly planar.
