Reduction kinetics of combusted iron powder using hydrogen
The reduction kinetics of iron oxides fines by hydrogen was investigated using thermogravimetric analysis in the temperature range of 400–900 °C. The powder, consisting of a mixture of hematite and magnetite, was produced by combustion of iron in air. During reduction, the removal of oxygen leads to formation of pores in the particles, and ...

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.
