Description
technical field [0001] The invention relates to a device for producing nano-bismuth oxide powder, in particular to a gasifier for producing nano-bismuth oxide powder with bismuth ingots. Background technique [0002] The production of nano-bismuth oxide powder has been produced by many domestic manufacturers, but in the past, domestic enterprises generally used chemical methods to produce nano-bismuth oxide powders. The production of nano-bismuth oxide powders by chemical methods has disadvantages such as high energy consumption, serious pollution, complicated equipment, and high investment. To overcome the above defects, we chose the plasma vapor phase method to produce nano bismuth oxide powder. Electric arc furnaces, especially plasma arcs, are more and more widely used in industry. We have used plasma arcs to prepare nano-scale powder materials of "silver, zinc, antimony, zirconium" and other metal materials, and all have been successful. However, when using the same eq...
