Zinc Metal Powder, 325 Mesh, Lab Grade

Zinc Metal Powder, 325 Mesh, Lab Grade

Zinc metal dust or powder possesses a grayish shiny appearance, has no odor, and is practically insoluble in water at ambient conditions. It is brittle at ordinary temperatures and is found naturally in rocks, animals, plants, soil, and volcanic dust/gases. It produces toxic Zinc Oxide fumes when heated to very high temperatures or undergoes ignition. Its principal ore is named Sphalerite, which is a sulfide derivative of Zinc. It can be produced in two ways from its ore. The first method involves the roasting of ore in the presence of air to produce zinc oxide, which is then heated with Coke or Coal to around 1,100 °C producing metallic Zinc. The second method involves the leaching of roasted Zinc Oxide with Sulfuric Acid, followed by electrolysis to produce Zinc Metal. Laboratory Reagent (LR) and Chemically Pure (CP) are the two terms often used to describe Lab Grade chemicals. Lab Grade chemicals do not meet any accepted quality or purity requirements such as the ACS Grade, the USP Grade, and the FCC Grade, despite their acceptable purity.
