Abstract
Sintering temperature of BaTiO3 is reduced by addition of LiF, increasing the Ba/Ti ratio and decreasing the starting particle size of BaTiO3. Li and F are contained not only in BaTiO3 grains, but also in grain baundaries. The quantity of them decreased by increasing firing temperature, because of vaporizatin of LiF, and also is dependent on the Ba/Ti ratio which affects the reaction mechanism in firing process.
