Zinc oxide is used as an additive in a variety of materials and products, including plastics, ceramics, glass, cement, lubricants, paints, adhesives, etc. There are three main methods for producing zinc oxide: direct method, indirect method, and wet method. The direct method is to roast zinc concentrate to reduce sulfur and other substances, then mix it with adhesives, coal powder and other substances, and then put it into a furnace for heating, so that the zinc in the zinc-containing raw material becomes zinc vapor, and then the zinc vapor is contacted with oxygen to oxidize the zinc into zinc oxide.
