Key Properties
Zinc dust (CAS No. 7440-66-6) is a fine gray-blue metallic powder that serves as a highly effective reducing agent in various chemical reactions. This AR-grade zinc dust is characterized by its high purity of 98%, making it suitable for analytical and laboratory applications where precision is critical. Zinc is a transition metal known for its ability to donate electrons, which is essential in reduction reactions. Its applications extend beyond organic synthesis to include use in galvanization, batteries, and as a pigment in paints.
Also known as Zinc powder, Zinc metal dust.

- Substance
Zinc dust appears as a fine gray-blue powder with a metallic luster. It has a density of approximately 7.14 g/cm³ and a melting point of 419.5 °C. The boiling point of zinc is around 907 °C. Zinc dust is insoluble in water but can react with acids to release hydrogen gas. It has a flash point of 200 °C, indicating that it can ignite under certain conditions, particularly when in a fine dust form. The particle size typically ranges from 1 to 100 micrometers, which enhances its reactivity in chemical processes.

Zinc dust is widely used in organic synthesis as a reducing agent, particularly in the preparation of various organic compounds. It is also employed in the production of zinc-based alloys and as a protective coating for metals to prevent corrosion. In the pharmaceutical industry, zinc dust is utilized in the synthesis of active pharmaceutical ingredients (APIs). Additionally, it finds applications in the manufacture of batteries, where it serves as an anode material, and in the production of paints and coatings for its anti-corrosive properties.
