Effect of Ba:Ti Ratio on Densification of LiF‐Fluxed BaTiO3.

The literature on LiF-fluxed BaTiO3 has shown substantially lower sintering temperatures compared to that of unfluxed BaTiO3. In an effort to understand densification behavior in this system, shrinkage was studied for various Ba: Ti ratios and 2 wt% LiF additions. Sintering of BaTiO3 with LiF is sensitive to the Ba:Ti ratio. Excess Ba reduced the sintering temperature and increased the fired bulk density. The starting powder stoichiometry, net Ba:Ti ratio, and addition of LiF appear to be independently important.
