How To Make Iron Oxide Powder
Method of making iron oxide powder
To make iron oxide powder, first prepare all the things. Iron filings, acid, etc. are all necessary. The iron filings should be pure, and less impurities are better; the acid should be of an appropriate amount and suitable type.
First place the iron filings in the vessel and slowly inject the acid. At this time, the reaction can be seen gradually, and bubbles emerge. It is necessary to carefully observe the reaction state and control its rate. Do not overdo it. Wait for the reaction to slow down and let it stand for a while to allow the debris to settle.
Then, take the supernatant and put it in another container. Add an appropriate amount of precipitant to this supernatant. The amount of precipitant, when accurately grasped, is less than incomplete precipitation, and more or impurities. When the precipitate is formed, let it stand again, so that the precipitate can settle firmly at the bottom of the vessel.
Then, filter it with filter paper to separate the precipitate from the liquid. The precipitate is the first iron-containing compound obtained. Place the precipitate in a clean crucible and roast it at a moderate temperature. When roasting, pay attention to the change of the heat. It should not be too strong to cause its qualitative change, nor should it be too weak and not roasted thoroughly.
After a certain period of roasting, take out the crucible and wait for it to cool. At this time, the resulting powder is iron oxide powder. However, it needs to be tested again to observe its purity, particle size, etc. If it does not meet the needs, it can be processed according to the situation. In this way, high-quality iron oxide powder is obtained.
