Abstract

Electrolytic manganese residue (EMR) is an acid filter residue and contains a large amount of hazardous substances. The plasticity and sintering properties of EMR heated at 920-1020 are measured. EMR primarily consists of quartz (SiO2) and chemical gypsum (CaSO4·2H2O), and has a high plasticity. The water absorption and porosity increased but the density and the bending strength decreased with the sintering temperature rising at 920–980. Inversely, the water absorption and porosity of sample decreased but the density and strength increased at 980–1020, and it has the maximum density (1.439 g/cm3) and maximum strength (8.7 MPa). Once sintered above 980, some liquid phases appear and lead to shrinkage and cracking, indicating the failure of continuous sintering.
