Mullite-zirconia composites with 2-6 mol% yttrium oxide have been prepared from Indian coastal sillimanite beach sand, zirconia and alumina. All raw materials have been attrition milled and then isostatically pressed followed by sintering in the range of 1500-1600 degreesC with a 2-h soaking period. Then the sintered materials have been characterised in terms of bulk density, linear shrinkage, hot modulus of rupture, X-ray diffraction, infra red spectroscopy and microstructural features. The effect of yttrium oxide with change of sintering temperature for different properties have been discussed. (C) 2002 Published by Elsevier Science Ltd and Techna S.r.l.
