Abstract
The rising demand for Cu entails increased demand for refractory materials. In this work, we show the corrosion of novel Cr-free Al2O3-MgAl2O4 refractory material for copper industry against PbO-rich copper slags. The FactSage simulations were conducted to reveal changes in a phase composition of the corroded material. Corrosion was tested experimentally by hot stage microscopy up to 1450 °C, powder and contact corrosion test at 1300 °C. Corroded materials were characterized in terms of phase composition by XRD, and alternations in microstructure by SEM/EDS. The results showed that, the passive corrosion mechanism predominates, with the formation of platelet-morphology PbAl12O19 and complex spinel (Mg,Fe,Cu,Zn)(Al,Fe)2O4. PbO-richest slag is the most aggressive towards refractory.
