| Description |
Mullite-zirconia composites were prepared from Indian zircon flour and calcined alumina following the reaction sintering route. Zircon hour and calcined alumina with 0-4.5 mol% dysprosium oxide were attrition milled followed by isostatic pressing and sintering at 1400-1650 degrees C for 2 h. Significant densification was achieved after dysprosia addition as an additive. The thermal expansion coefficient values were found to be reduced in the presence of dysprosia. Dysprosia helps in densification by liquid phase formation as well as by stabilisastion in tetragonal zirconia state. The thermo-mechanical and microstructural characteristics of the composites were discussed.
