An almost-spherical BaTiO3 approximately 2.0 mm in diameter was synthesized using an aerodynamic levitator. The densities of the undercooled liquid BaTiO3 were measured from high speed video images of a molten droplet. The densities of the undercooled liquid phase were 4.2~4.0 g/cm3 at temperatures ranging from 1622 K to 1693 K. The aerodynamic levitation technique provided an effective method for determining the thermophysical properties, such as the density and volumetric thermal expansion coefficient of the material.
