What is Cobalt?
Discovered by Georg Brandt in the 18th century, cobalt is vital in today’s technology, found naturally alongside copper and nickel. It’s crucial for lithium-ion batteries, aerospace, and healthcare.
Cobalt, with the chemical symbol Co and atomic number 27, is primarily sourced from ores like cobaltite and erythrite, as well as from byproducts of copper and nickel mining. The refinement process involves extraction methods such as smelting or hydrometallurgical processes, followed by purification to obtain high-purity cobalt for industrial use.
Cobalt exhibits ferromagnetic properties, ideal for high-performance applications in magnetic materials and electronics. It demonstrates excellent corrosion resistance, particularly in high-temperature environments. Exceptional hardness and strength make it highly sought after for wear-resistant applications, often alloyed with other metals to enhance material performance. Cobalt-based alloys offer superior strength, temperature resistance, and corrosion resistance, making them invaluable across applications.
