High-Temperature Strength and Form Stability of Compact and Cellular Carbon-Bonded Alumina

“…Similar to the above-mentioned studies, the filter materials exhibited brittleness at 1100 °C and ductility at 1500 °C with considerable compression strengths at both temperatures. Hence, even after contact with steel melt, the [17]. Please note that the tests shown in (b) were interrupted shortly before 8% compression due to machine limitations mechanical behavior of the specimens was not significantly influenced.…”

“…During the thermomechanical testing, this gap caused a wall-slip effect between the coating and substrate. To examine the residual thermomechanical properties of Al 2 O 3 -C foam filters coated with carbon-containing calcium dialuminate (CA 2 -C) or calcium hexaaluminate (CA 6 -C) after contact with steel melt, the filters were immersed into steel melt under argon atmosphere in a metal casting simulator at 1650 °C for 10 s [17]. Compression tests were then performed on these residual filters at 1100 °C and 1500 °C (Fig.…”
