Abstract
According to both the first principle and materials chemistry, an innovative method for fabricating of the Ca1-xSrxTiO3 ceramics was investigated. Ca1-xSrxTiO3 was sintered at temperatures as low as 980 Degree C by adding 1.0 wt % Li2Si2O5 without forming a grain boundary phase. It was considered that the sintering was promoted by self-accelerated diffusion due to the formation of point defects caused by doping with Li2Si2O5. Consequently, a new concept of non-stoichiometrically activated sintering, which is enhanced by point defects without the help of a grain boundary phase, is systematically studied for the first time in the Ca1-xSrxTiO3- Li2Si2O5 system.
