Analysis of direct reduced iron (DRI) by X-ray diffraction

This application note describes the benefits of X-ray diffraction (XRD) to the quantitative determination of the phase content and the calculation of process critical parameters for the production of direct reduced iron (DRI).

Direct reduced iron (DRI), also called sponge iron, is produced by the reduction of iron ore (in the form of lumps, pellets or fines) with a reducing gas produced from natural gas or coal. This process is called direct reduction.
