Used as a catalyst in hydrogenation and reforming reactions, including syngas production from natural gas, in the petrochemical industry.

Employed in the production of nickel-based batteries, especially in nickel-cadmium (Ni-Cd) and nickel-metal hydride (Ni-MH) types, due to its electrical conductivity and chemical stability.

Serves as a pigment for ceramics and glass, imparting green, brown, or greenish-gray colors depending on the composition, and used as a light filter in specialty glass like sunglasses.

Utilized in the electronics industry for manufacturing thermistors, other ceramic components, and magnetic materials such as ferrites for transformers, inductors, and small electronic devices.

Applied in fuel cells as an electrode material due to its electrochemical stability.

Used in the synthesis of specialty alloys and in electroplating processes to improve corrosion resistance.
