Grain growth during sintering of batio3 with lif

The sintering behavior of BaTiO3 with LiF showed that it was possible to sinter barium titanate at temperatures below 1000 degrees C. Different combinations of the sintering powders were prepared by adding 1 to 5 w% LiF and sintering at the temperature of 950 degrees C for 20 hours. The grain growth of LiF fluxed BaTiO3 was studied, and electron microscopy was used to investigate and characterize the microstructure of the samples. The dielectric constant and dielectric losses were determined. It was shown that the composition of the liquid phase formed during this process had a prominent influence on the grain growth and on the formation of BaTiO3 with better dielectric properties
