Research and Development of Novel Refractory of MgO Doped with ZrO(2) Nanoparticles for Copper Slag Resistance
This study investigates the corrosion mechanism on 100 wt.% MgO and 95 wt.% MgO with 5 wt.% nano-ZrO(2) ceramic composites. First, MgO powder and powder mixtures (MgO + nano ZrO(2)) were uniaxially and isostatically pressed; then, they were sintered at 1650 °C. Corrosion by copper slag was studied i...

description | This study investigates the corrosion mechanism on 100 wt.% MgO and 95 wt.% MgO with 5 wt.% nano-ZrO(2) ceramic composites. First, MgO powder and powder mixtures (MgO + nano ZrO(2)) were uniaxially and isostatically pressed; then, they were sintered at 1650 °C. Corrosion by copper slag was studied in sintered samples. Physical properties, microstructure, and penetration of the slag in the refractory were studied. Results reveal that ZrO(2) nanoparticles enhanced the samples’ densification, promoting grain growth due to diffusion of vacancies during the sintering process. Additionally, magnesia bricks were severely corroded, if compared with those doped with nano-ZrO(2), mainly due to the dissolution of MgO grains during the chemical attack by copper slag. |
