The partial replacement of primary raw materials for the production refractories with recycled ones gains in importance, as it contributes to conservation natural resources, energy saving, and reduction greenhouse gas emissions. In this work, use a magnesia–carbon (MgO-C) recyclate fractions 3–6, 1–3, 0–1 mm material MgO-C was investigated. examined via optical scanning electron microscopy. Usi...

Environmental issues regarding Cr6+ formation lead to replacing chrome-containing refractories with greener alternatives. MgO-containing compositions have been extensively investigated for this purpose, however, few studies evaluated the likelihood of using other chemical elements as inducers spinel-like phase in refractory castables. In study, addition zincite alumina-based castables was and c...
