Abstract
Direct fabrication of ceramics from solutions has been developed in our group. Here we have developed another innovative process: Casting of multi-components melt to fabricate multi-phases ceramics nanocomposites. Near eutectic compositions in appropriate pseudo-ternary systems like ZrO2 (or HfO2)-Al2O3-ABO3(perovskite) have been chosen. These samples were rapidly solidified after melting. They have given in-situ nanocomposites of three phases, or an amorphous bulk which can be changed into nanocrystalline bulk composites by appropriate annealing. Those methods should have huge potential in wide application areas.
