  • Applications

    Nickel oxide (NiO) is used as a colorant in ceramic glazes and glass, imparting brown to green hues depending on the formulation; it serves as a catalyst or catalyst precursor in industrial processes, commonly used in hydrogenation and reforming and in nickel-based catalytic systems supported on oxides and subsequently reduced to metallic nickel; it acts as an active material in energy storage, notably as part of nickel oxide hydroxide (NiOOH) electrodes in alkaline rechargeable batteries and related devices; it is employed in gas-sensing applications as a p-type metal-oxide semiconductor for detecting reducing gases such as CO and H2; and it is used in coatings and inks as a pigment additive to control color in industrial finishes.
