“…In our previous work, lightweight Al 2 O 3 ‐MgAl 2 O 4 refractories with guaranteed mechanical properties and low thermal conductivity were obtained due to the density gradient structure existing in the matrix of refractories 9‐11 . Considering the service environment of these refractories, besides mechanical strength, thermal shock resistance was also an important issue.…”

“…12,13 The potential of using lightweight refractories as the energy-saving working linings of high-temperature furnaces had been widely recognized, and this strategy has attracted significant commercial interest. [14][15][16][17] Lightweight refractories for furnace linings are usually designed by the ways of structural improvement of refractory lining, 18 forming micropores by in situ decomposition, 19,20 using lightweight aggregates, 21 and so on. Although lightweight refractories have better thermal insulation performance than dense refractories, their slag resistances and mechanical properties are the limiting factors that restrict their wider application.…”

“…In order to make a trade‐off between thermal conductivity and slag resistance, much effort has been put into the optimization and development of lightweight aggregates, such as the increase of closed porosity and the homogenization and nanocrystallization of pore size 14–17 . At the same time, the preparation of lightweight refractory bricks possessing gradient density provides the academic world and the industrial world another path to realize the lightweight refractory 18–20 . In our previous studies, the refractory with density‐gradient structure has been proved that it has guaranteed mechanical and slag resistance compared to dense one 21 .…”
