Abstract :
It is shown that nanocrystalline barium titanate can be obtained from high-energy ball-milling of conventional commercially available barium titanate powder. X-ray investigations, surface determination, and dielectric studies have been carried out on several samples obtained with different periods of grinding. It is found that stabilization of the cubic phase at room temperature occurs for values of grain size and coherently diffracting domain size lower than 0.12 μm and 2.5×102 Å, respectively
