The physical properties of cobalt ferrite spinel are linked to the cation distribution over the tetrahedral sites A (8a) and octahedral sites B (16d) of the structure. Cobalt is silver-white in color with a bluish tinge. Co-Cr alloys show high resistance to corrosion due to the spontaneous formation of a protective passive film composed of mostly Cr 2 O 3, and minor amounts of cobalt and other metal oxides on the surface. Soluble in acid, insoluble in water, alcohol, ammonia. Cobalt is one of those often-neglected metals with a host of uses, interesting facts, and dynamic properties. When heated to 300 ° C or higher in air, it oxidizes to form CoO, and when it is white, it burns to Co3O4.
