Zirconia dispersed mullite composites have been prepared from zircon flour and calcined alumina by reaction sintering. The raw materials have been characterized by chemical analyses, particle size distribution and X-ray diffraction. The batched raw materials have been attritor milled, uniaxially pressed and fired between 1450° and 1650°C with 2 hrs soaking time. The effects of MgO and Y2O3 additives on bulk density, porosity, rate of shrinkage and thermal expansion have been studied. Results indicate that the rate of shrinkage is higher in composites with additives and this shrinkage commences at a lower temperature as compared to that without additive. The thermal expansion and shrinkage behaviour are discussed.
