Microstructural features of fusion cast Al2O3-ZrO2-SiO2 refractories

Interaction mechanism between refractory and melts in iron bath smelting reduction process

“…ZrO 2 has been used in metallurgy industry and refractory production as an addition materials for many years [7,11]. The refractory brick containing ZrO 2 has been widely used in high temperature furnace or kiln.…”

“…They are widely used in blast furnace, convertor, electric arc furnace [7,8,[10][11][12][13][14][15]. But it is imperative to investigate the corrosion mechanism of different refractories in the melts of smelting reduction with iron bath, to control the corrosion reaction and to decrease the corrosion rate of refractories efficiently.…”

Powder and Part Characterizations in Electron Beam Melting Additive Manufacturing

“…One example is the production of fusion cast alumina-zirconia refractories, which exhibit special resistance to corrosion in contact with molten glass and are used in its production. 43,44 However, the general approach to casting in ceramics is the production of green powder compacts that are subsequently thermally processed (i.e., fired) to produce dense parts with desired density, grain structure, and concomitant properties. The most venerated of these techniques is slip casting, which is widely used in the production of both artistic and engineering components.…”

Microstructural and mechanical consequences of thermal cycles on a high zirconia fuse-cast refractory

“…1 Compared to conventional sintered refractories, their specificity is related to the fabrication by melting that leads to very specific microstructures. 2,3 They are acknowledged to contain a continuous glassy phase distributed between several crystallised phases of complicated and convoluted shapes. This specific microstructure is the result of a slow and controlled cooling from the fusion at high temperature, called annealing.…”
