　　1. Atomization method Zinc powder produced by atomization method has fine particles and high active metal content. The specific production method is to melt and overheat the metallic zinc to about 660 °C, and atomize the zinc liquid into fine metal powder through a high-pressure gas medium. It can be seen that the production process of the atomization method is relatively simple, easy to operate, and low in cost. Atomization methods are divided into conventional atomization methods and combined atomization methods, but the average particle size of zinc powder produced by conventional atomization methods is larger, while the yield of fine powder is lower. The synthesis method is slightly more complex and has strict requirements on the process. In this way, the quality of zinc powder is higher, which is one of the commonly used zinc powder production methods.


　　2. Distillation-condensation method This method heats metallic zinc to over 1000℃ to volatilize zinc vapor, which is then condensed to obtain Zinc powder the product. The zinc powder produced has better activity, but this process requires higher quality raw materials.


　　3. Electrolysis method Zinc powder produced by electrolysis usually has a larger specific surface area and good activity, but due to environmental protection reasons, it is rarely used at present.


　　These are three commonly used methods for producing zinc powder. Shandong Xingyuan Zinc Industry Technology Co., Ltd. is a zinc oxide manufacturer , welcome to call for consultation.
