Cobalt Metal

Cobalt is a transition metal used in high-strength alloys, batteries, and pigments. Here’s a detailed specification of cobalt:

Chemical and Physical Properties:

• Chemical Symbol: Co

• Atomic Number: 27

• Atomic Weight: 58.93 g/mol

• Density: 8.90 g/cm³ at room temperature

• Melting Point: 1,495°C (2,723°F)

• Boiling Point: 2,927°C (5,301°F)

• Appearance: Silver-gray metal with a slight bluish tint

• Hardness: 5 on the Mohs scale

Industrial Uses:

1. Batteries: Cobalt is a key component in lithium-ion batteries, especially in electric vehicles (EVs), portable electronics, and energy storage systems.

2. Alloys: Cobalt is used in superalloys that are resistant to heat, corrosion, and wear, making it vital for aerospace and gas turbine engines.

3. Magnets: It is used in strong permanent magnets (Alnico and Samarium-cobalt magnets) for high-performance motors and generators.

4. Pigments: Cobalt compounds are used in ceramics and glass to create deep blue pigments.

5. Catalysts: Cobalt acts as a catalyst in petroleum refining and the production of synthetic fuels.
