  • Synthesis and sintering of chromium-free complex spinels

    Magnesia-chrome refractory ceramics are used in non-ferrous industry because of their corrosion resistance against fayalite-type slags rich in FeO. Unfortunately Cr³⁺ may oxidize to Cr⁶⁺ during the smelting and converting processes thus making their spent pot-lining hazardous. Two strategies are explored in this present work to develop chrome-free refractories sinterable at lower
