| Abstract |
| In the present investigation, five different types of calcined
alumina were incorporated in the formulation of mullite
shapes to have a compartative study of the materials. The
mullite comJ!ositions were pneumatically rammed at a pressure
of 100 kg.cm-2 and tired at 1420°C for 4 hours. The
results indicate mullite shapes possessing high spalling
resistances(+ 30 cycles water quenching from 1000°C to room
temperature) and improved cold crushing strengths after 25
cycles of spalling test. |
