Selection of Al2O3-SiC-C (ASC) Refractory Materials
· The biggest feature of β-Al2O3 as a castable binder is that it does not contain CaO. Because β-Al2O3 transforms into α-Al2O3 at high temperature the temperature of β-Al2O3 combined castable is higher exceeding 1700℃. After β-Al2O3 is hydrated AI (OH)3 and AlOOH are formed which can play the role of cementing and hardening.
