| ABSTRACT |
|
LAS system, which is difficult to be sintered, was densified by using the powder synthesized from metal alkoxides. Sinterability, thermal and mechanical properties were improved through synthesizing the complex oxide powder from the addition of Ge as an alkoxide. As a result, the synthesizing and sintering temperature of the LAS system lowered by about 10$0^{circ}C$ and its modulus of rupture (MOR) increased twice higher compared to the sample from the oxide by the direct method. |
