An efficient and flexible chemical co-precipitation method has been used to synthesize nanoscale Al2O3-GdAlO3 powders with eutectic composition. The as-synthesized powders exhibit a highly dispersive and homogeneous distribution with an average particle size of 50nm. The phase transition in the resulting powders strongly depends upon the calcination temperature. GdAlO3 undergoes complete crystallization...
The directionally solidified Al2O3/MgAl2O4/ZrO2 ternary eutectic ceramic was prepared via induction heating zone melting. Smooth Al2O3/MgAl2O4/ZrO2 eutectic ceramic rods with diameters of 10mm were successfully obtained. The results demonstrate that the eutectic rods consist of Al2O3, MgAl2O4 and ZrO2 phases. In the eutectic microstructure, the MgAl2O4 and Al2O3 phases form the matrix, the ZrO2 phase...
