Aluminum Powder (Al)
Aluminum Powder (Al) is a fine, silvery-gray, highly reactive metallic powder composed of aluminum particles, ranging from nanometers to hundreds of micrometers. Due to its high surface area, it is combustible, often used in explosives, pyrotechnics, rocket fuel, pigments, paints, and thermite reactions to produce high heat.
Chemical Formula: Al
Description: Silvery-white to gray, odorless, finely divided metallic powder. It is highly reactive, flammable, and often coated with fatty acids or oil to prevent premature oxidation.
Key Uses:
- Pyrotechnics & Energetics: Used in fireworks, rockets, and solid propellants.
- Industrial Processes: Used in thermite reactions (aluminothermics), catalysts, and chemical synthesis.
- Coatings & Inks: Acts as a metallic pigment in paints and coatings.
- Manufacturing: Used in additive manufacturing (3D printing) and metal alloys.
It is important to note that aluminum powder is a strong reducing agent and can form explosive mixtures with air or oxidizing agents.
