Abstract
The purpose of the authors investigations is to clarify the interaction of BaTiO3X with Li compounds during liquid phase sintering, the chemical inhomogeneity of the resulting microstructure-property relationships. It is shown that the onset of densification in the flux systems studied can be directly correlated with the temperatures at which a eutectic liquid forms. The lower sintering temperatures of Ba-excess compositions (due to BaCO3X) is clearly due to the eutectic liquid which forms at 610 C, compared to 700 C when BaCO3X is not present. TEM micrographs reveal BaTio3X sintered with 2% weight LiF (Ba/Ti=1.02) at 900 C for 2 hours results in a grain core(tetragonal)-shell(cubic) structure.
