Cobalt
Found in Group 9 of the periodic table with atomic number 27, cobalt is a ferromagnetic metal, meaning it can be magnetized like iron. While it makes up only about 0.001% of the Earth's crust, its physical characteristics make it uniquely valuable:
While historically prized for its color, cobalt's primary demand today is driven by technology and clean energy. 1. Electric Vehicle (EV) Batteries cobalt
: A shiny, gray-white metal that takes on a distinctive deep blue hue when oxidized and used in compounds. Historical Significance: From "Goblins" to Fine Art Found in Group 9 of the periodic table
The name "cobalt" originates from the German word kobold , meaning "goblin" or "evil spirit." Medieval miners in Saxony often found ores they thought contained copper or silver, but which instead released poisonous arsenic fumes when smelted. They blamed these "goblins" for the deceptive and dangerous rocks. Electric Vehicle (EV) Batteries : A shiny, gray-white
Because it retains its strength at extreme temperatures, cobalt is alloyed with other metals to create . These are critical for the turbine blades in jet engines and gas turbines, where heat resistance is a matter of safety and efficiency. 3.
