The classical technique for production of iron powder is the reduction of iron oxide. 29. Theory of the process: It is the oldest process of production of iron powder by using carbon as the reducing agent. In this process pure magnetite (Fe3O4) is used. Coke breeze is the carbon source used to reduce iron oxide.

Some tests unique to powders may also be used. For example, an iron powder may have an unknown percent of iron oxide, (Fe 2 O 3). A test sample of the iron powder is taken and exposed to a stream of hydrogen. Weight loss that occurs in the sample is measured. From this, the percentage of iron oxide present in the powder can be calculated.
