Used as a catalyst in chemical reactions, especially in hydrogenation and oxidation processes. Commonly applied in rechargeable batteries, such as nickel-cadmium and nickel-metal hydride types, due to its electrochemical properties. Employed in the production of specialty ceramics and glasses, providing color and enhancing thermal stability. Utilized in fuel cells as an electrode material because of its conductivity and durability at high temperatures. Also found in coatings and pigments for electronics and construction materials where resistance to heat and corrosion is required.
