Influence of TiO 2 - and ZrO 2 -addition on the interaction of alumina castable with molten coal and gasifier slag

Formation of liquid‐phase isolation layer on the corroded interface of MgO/Al2O3‐SiC‐C refractory and molten steel: Role of SiC

“…[1][2][3][4][5][6][7][8][9] The above works led to a more in-depth understanding of refractories' service performances and structures. [10][11][12][13] Building on these works, a further structural optimization for prolonging refractories' service cycle was carried out. [14][15][16][17][18][19][20] Nowadays, the marketing demand for high-quality steel continued to grow, and the proportion of secondary refining in steelmaking process kept to drastically increase.…”

Preparation of Zr4+ doped calcium hexaaluminate with improved slag penetration resistance

“…Compared with slag layer, the amount of spinel with typical cubic morphology in corrosion layer significantly increases as shown in Figure 14D. It has been reported that the presence of Zr can promote the formation of spinel for alumina‐based refractories when in contact with slag 30,32 . The generation of MA can indirectly increase the relative content of SiO 2 in slag.…”

Degradation mechanism of Cr2O3‐Al2O3‐ZrO2 refractories in a coal‐water slurry gasifier: Role of stress cracks

“…A deeper understanding of corrosion behavior/mechanism is vital to the prediction of the stability, reliability and overall service performance of chromite containing refractories. To date, the corrosion behaviors of chromite‐containing refractories in gasifiers have been investigated under some specific conditions . It should be pointed out that the degradation of refractories in a commercial gasifier is resulted from, and thus dependent upon, the synergistic attack from several processing parameters, for example, high pressure/temperature, mechanical failure, complex atmosphere, and prolonged testing time.…”

“…To date, the corrosion behaviors of chromite-containing refractories in gasifiers have been investigated under some specific conditions. [27][28][29][30][31] It should be pointed out that the degradation of refractories in a commercial gasifier is resulted from, and thus dependent upon, the synergistic attack from several processing parameters, for example, high pressure/temperature, mechanical failure, complex atmosphere, and prolonged testing time. So it would not be possible to reproduce such degradation behavior via laboratory scale testing, though it is considered to be useful for evaluating service performance of potential lining materials, assisting selection of a suitable refractory system.…”
