| Research Abstract |
The paper a ims to produce the new ceramics fabrication process through the transformation from the metastable to the equilibrium eutectic structure. The mechanism for the metastable/ equilibrium transformation was discussed based on a thermodynamic approach including the strain energy. In the eutectic system which has Al_2O_3 and perovskite and garnet phases, the effect of kinds of perovskite on the transformation was also examined The Ce doped eutectic casting was demonstrated to be used as a phosphor.
