| Abstract: | Oxide eutectic ceramics prepared by the directionally solidified micro-pulling down method are reviewed, meanwhile different oxide euteetie fibers and rods prepared by u-PD from binary and ternary euteetie systems are introduced. It is obtained that by simply modifying crucible, bulk crystals with well mierostruetures and mechanical properties can be achieved using u-PD method. |
| Keywords: | eutectics directionally solidification micro-pulling down method crucible pull-rates |
