General description

Nickel(II) sulfate hexahydrate is a hydrated nickel salt. Its thermal decomposition in the presence of air and helium has been studied. Its crystals exist in monoclinic and tetragonal polymorphic forms.

Application

Nickel(II) sulfate hexahydrate may be used in the preparation of NiFe2O4 nanoparticles (NPs), which are required for the fabrication of a glucose biosensor.
