Abstract
Eutectic composites of lamellar ZrO2-CaO and ZrO2-NiO and fibrous Al2O3-ZrO 2, Al2O3-ZrO2(Y2O3), ZrO2-MgO and CaF2-MgO wide gap materials have been gro wn from the melt by unidirectional solidification using laser floating zone and Bridgman techniques. The unique microstructure and interface morpholog y of these composites led to some remarkable mechanical (strength and tough ness), optical (light guiding) and transport (ionic conduction) properties. The underlying relationships between microstructure and properties were br iefly discussed in each case in the light of some possible applications of these eutectics. (C) 2000 Acta Metallurgica Inc.
