Zochem offers a variety of zinc oxide powders and pellets with purities of 99.9% and beyond, manufactured for specific market applications. Pelletized zinc oxide is an excellent option for production applications requiring high flow rates.
Based on the French Process, we start with pure metallic zinc. The metal is vaporized and oxidized in a combustion zone, utilizing our natural gas fired muffle design furnace. This typically yields consistently nodular shaped granules. Products are available with surface areas ranging from 2.7 m2/g to 10.0 m2/g. With multiple surface area options, coated and uncoated granules and purity options, Zochem has a product for virtually any application. Custom formulations are also available. A wide variety of packaging options are available with customized packaging as an additional choice. Zochem also has the ability to add liquid coatings through different mixing and blending equipment.
