Nickel(II) oxide (Cat No.: M047852) is an inorganic compound that appears as a green to black crystalline solid and is the most stable oxide form of nickel. It has a rock-salt crystal structure and is insoluble in water but reactive in acidic or reducing environments. NiO is widely used in ceramics, glass, batteries, and catalysts, particularly in nickel-cadmium batteries, electrochromic devices, and fuel cells. It also serves in electronic materials and magnetic applications. Nickel(II) oxide is classified as potentially toxic and requires careful handling.
