Department Of Materials Science And Engineering, Obafemi Awolowo University Ile-Ife, Nigeria . ABSTRACT This study focuses on the characterization of cold briquetted iron (CBI) using powder diffraction techniques. CBI is under-sized metallic fines produced during the direct reduction process (DR-process), which are made into briquettes when they are cold using sodium silicate and lime as binder and flux respectively. Powder sample of CBI was prepared by crushing and grinding some of the briquettes and sieved through 30-microns aperture. Thereafter, the constituent phases in the sample were identified using X-Ray Powder Diffraction (XRD) techniques and scanning electron microscopy. It was observed ...
