Key words: synthesis of barium titanate, subcritical water fluid, barium titanate nanocrystals
The structure and morphology of fine-crystalline barium titanate synthesized in a
subcritical water fluid at 230 °C and 2.9 MPa were studied. Barium oxide, barium hydroxide
octahydrate Ba(OH)2 ⋅ 8H2O and two modifications of titanium dioxide (rutile and
anatase) were used as starting reactants. Relationships between the composition and
properties of the reactants and the characteristics of the product (barium titanate)
were revealed. They indicate that the product structure in the subcritical water is
formed via a solid-phase mechanism.
