Zinc Dust Extra Pure is a fine bluish-silver metallic powder primarily composed of elemental zinc with minimal impurities. It serves as a critical reagent and raw material in laboratories and industries, especially in metallurgical, chemical synthesis, and galvanizing applications. Its high surface area and reactivity make it valuable for redox reactions, zinc assays, and protective coatings. The dust form requires careful handling due to potential dust explosion hazards and reactivity with acids producing flammable hydrogen gas. Storage in dry, controlled conditions with appropriate PPE is essential for safe use. This zinc dust meets high purity standards suitable for research, manufacturing, and environmental applications such as water treatment and soil conditioning.
