Effect of mullite microcrystal on phase change mechanism of anorthite-based ceramics at low temperatures using electrolytic manganese residue (opens in new tab)

Electrolytic manganese residue (EMR) has caused severe pollution due to its high concentration of water-soluble contaminants, posing a major obstacle to the sustainable development. To address the low utilization of EMR and its associated pollution, mullite-enhanced anorthite ceramics were successfully prepared at temperatures below 1200 °C by using EMR and calcined kaolin (CK). Different EMR/CK ratios, sintering temperatures, and holding times were investigated. The optimal bending strength ...
