MgO-ZrO2 refractory ceramics based on recycled magnesia-carbon bricks

Optimized preparation of MgO-ZrO2 nanocomposite powders by assisted sol-gel method

“…Therefore pure zirconia cannot be applied to the preparation of ceramic products. The addition of stabilizers such as Y2O3, MgO, CaO, and CeO2 is an effective measure to stabilize the tetragonal phase zirconia at room temperature [4][5][6][7]. Y2O3 is the most widely used, but yttrium oxide stabilized zirconia ceramics suffer from low-temperature ageing, which strongly limits their application in areas such as bioceramics, and there are few reserves of Y2O3, which is not conducive to sustainable development.…”

“…Y2O3 is the most widely used, but yttrium oxide stabilized zirconia ceramics suffer from low-temperature ageing, which strongly limits their application in areas such as bioceramics, and there are few reserves of Y2O3, which is not conducive to sustainable development. The MgO stabilized zirconia ceramics have excellent performance in both low-temperature and humid environments and high-temperature environments [5] and have good prospects for application in areas such as bioceramics and refractory materials, and raw materials such as MgO are abundant and readily available.…”
