Microstructures and mechanical properties of Al2O3–C refractories with addition of microcrystalline graphite

Effects of TiO2 addition on the phase, mechanical properties, and microstructure of zirconia-toughened alumina ceramic composite

“…For the ZTA -7 wt % TiO 2 sample however, the crack propagation encountered a higher number of crack deflection. Crack deflections are known to strengthen ceramic composites [23][24][25][26][27]. The increase in the fracture toughness from 5.93 MPa.¥m (0 wt% TiO 2 ) to 6.64 MPa.¥m (7 wt% TiO 2 ) could be explained by the mainly intergranular propagation path.…”

In-situ synthesis mechanism of plate-shaped β-Sialon and its effect on Al2O3–C refractory properties

“…For example, Yamaguchi [9] reported that the metallic Al in Al 2 O 3 -C refractories could produce Al 4 C 3 whiskers, which increased the bending strength significantly compared with the function of metallic Si. Wang et al [10] found that Al 4 C 3 and AlN whiskers can be formed at 1000 1C and numerous SiC whiskers can also be generated at 1200 1C. These bonding phases could improve the hot strength of lowcarbon-content refractories.…”

Effect of mixing on the properties of nanocarbon containing Al2O3‐C continuous casting refractories

“…The refractories used in the steel casting operations are generally made up of alumina‐carbon system, especially in the flow control devices like slide gate plates, submerged entry nozzles, monoblock stopper rods, and ladle shrouds, because of their excellent thermal and mechanical properties . Alumina is the major constituent in this class of refractories, which is necessary to provide mechanical and thermomechanical properties.…”
