Experiments were conducted to optimize the growth parameters of perovskite
structure of sodium tantalate in energy efficient hydrothermal process. We have
succesfully grown sodium tantalate nanocubes at low temperature of 140oC for
15 hours in rich alkaline atmosphere. It contains orthorhombic crystal system of
perovskite structure with an average size of 80 nm. The morphological, compositional,
structural, and thermal properties of as-synthesized nanocubes were
characterized by scanning electron microscope (SEM), x-ray powder diffraction
(XRD), and thermal gravimetric analysis (TGA) techniques.
