    Production method 

    Zinc Oxide in direct 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.


    Application:

    It is used in Natural rubber, synthetic rubber and latex active agent. It is also used as a reinforcing agent and colouring agent, and can also be used as a vulcanization agent for chloroprene rubber and a synergist for improving thermal conductivity. Also it is widely used in all kinds of rubber products, especially for transparent rubber products and food contact products.
