Application of iron powder:

One of the most important metal powders in the powder metallurgy industry. Iron powder is the largest amount used in powder metallurgy production, and its consumption accounts for about 85% of the total consumption of metal powder. The main market for iron powder is the manufacture of mechanical parts, which require about 80% of the total iron powder production. Displaced iron powder is mainly used to extract metals (copper, chromium, titanium, etc.) in various solutions, such as sponge copper production industry (extraction of copper from copper sulfate solution), commonly known as wet smelting. The displacement reaction replaces the positively charged metal from the solution with a metal having a large negative polarity. The larger the potential difference between the two metals, the larger the substitution tendency, such as the negative charge of iron in the displacement reaction of the production of sponge copper. Larger than copper, the positions of the two metals are interchanged at the reaction interface to achieve the purpose of extracting metal from the solution. Displacement of the medium metal is the key to improve the replacement rate, and the iron powder dedicated to the replacement aspect is a universal replacement medium metal currently engaged in the wet smelting industry.

Preservatives are placed in food packaging. The main component is iron powder. The role of iron powder is simply to absorb water and oxygen at the same time. Generally, the desiccant can only absorb water. When the iron powder particles are very small, they can quickly absorb water and oxygen. Such iron powder becomes reduced iron powder, which is grayish black powder.
