Activate Zinc Oxide (ZnO) particle size between 1-100 nm, is a new type of high-function fine inorganic product facing the 21st century, showing many special properties, such as non-migration, fluorescence, piezoelectricity, The ability to absorb and scatter ultraviolet rays, etc., can be used to manufacture gas sensors, phosphors, varistors, ultraviolet shielding materials, image recording materials, piezoelectric materials, piezoresistors, high-efficiency Catalysts, magnetic materials and plastic films, etc.
1. The raw material and preparation process of the direct method are relatively lower, and the quality and performance of zinc oxide are significantly lower than those of the indirect method. Although the zinc content can reach 99.5%, it is made directly from ore, so The content of impurities and heavy metals is very high! The resistance to yellowing and toxicity are also great.
2. The raw materials and preparation process selected by the indirect method are superior to those of the direct method, but the indirect method also has differences in the selection of materials, for example, 0# zinc ingots are better, with the highest purity, and 1#, 2# and other impurities have a large content , There are also manufacturers who use zinc slag to react to produce zinc oxide, which will also cause a certain gap between the quality and cost of the finished product.
3. Although they are all Zinc Oxide, the market claims that the content is 99.7%, what raw materials are used and what process is used for production, the final quality is very different, which is also the reason for the great price difference. It is also a place where the market is chaotic, substituting the second for the good, and the direct method for the indirect method!
