Active Zinc Oxide from Zinc Ash
Active Zinc Oxide Production from Zinc Ash, Secondary Zinc Waste & EAF Dust. Zinc Waste Utilization.
Active zinc oxide, with its unique physical and chemical properties, like high chemical stability, high electrochemical coupling coefficient, broad range of radiation absorption and high photo stability, may be a multifunctional material. With the wonderful properties, Active zinc oxide plays a very important role during a very wide range of applications varying from tires to ceramics, from pharmaceuticals to agriculture, and from paints to chemicals. Active zinc oxide are often classified into three types consistent with the production technique: indirect process, direct process and wet chemical change.

Active ZnO Applications:
In many applications, grades with high specific surface area allow more than remarkable savings because of their high reactivity and their excellent dispersion and fluidity properties.
The principal advantages of active zinc oxides are listed below:
Reduced ZnO usage in rubber applications with equal performance
Very high level of activity, even in very low concentrations
High level of purity: very low heavy metal content
Increased production capacity
Improved physical properties
Better resistance to compression set
Better aging resistance
Rubber
Coating
Ceramics
Pharmaceutical
Fertilizer
Electronics

Manufacturing Process:
For industrial use, ZnO is produced at levels of 105 tons per year by three main processes:
Indirect process: In the indirect or French process, metallic zinc is melted in a graphite crucible and vaporized at temperatures above 907 °C (typically around 1000 °C). Zinc vapor reacts with the oxygen in the air to give ZnO, accompanied by a drop in its temperature and bright luminescence. Zinc-Oxide particles are transported into a cooling duct and collected in a bag house. This indirect method was popularized by Le Claire (France) in 1844 and therefore is commonly known as the French process. Its product normally consists of agglomerated zinc oxide particles with an average size of 0.1 to a few micrometers. By weight, most of the world’s zinc oxide is manufactured via French process.
Direct process: The direct or American process starts with diverse contaminated zinc composites, such as zinc ores or smelter by-products. The zinc precursors are reduced (carbothermal reduction) by heating with a source of carbon such as anthracite to produce zinc vapor, which is then oxidized as in the indirect process. Because of the lower purity of the source material, the final product is also of lower quality in the direct process as compared to the indirect one.
Wet chemical process: A small amount of industrial production involves wet chemical processes, which start with aqueous solutions of zinc salts, from which zinc carbonate or zinc hydroxide is precipitated. The solid precipitate is then calcined at temperatures around 800 °C.
