The Fascinating World of Cobalt

Cobalt, a shiny gray metal, is known for its role in creating the blue pigment used in art and ceramics. Discovered by George Brand, cobalt's name comes from the German word 'kobolt,' meaning goblin. It is used in various applications, from pigments in art to industrial uses like superalloys for turbine blades and medical uses such as orthopedic implants. Cobalt is also significant in producing permanent magnets and lithium-ion batteries. Its radioactive isotope, cobalt-60, is used for sterilization and food preservation.
