Are barium films transparent and crack-free at 600 °C?

different barium sources were transparent and crack-free below 600 °C. Films prepared from tetragonal polycrystalline phase. In contrast, films prepared from the barium hydroxide precursor crystallized into the cubic phase at 600 °C. In addition, the films prepared from the precursors in alcohol-based solvents.

How does water affect the formation of barium precursor?

The incorporation of high concentrations of water in the sols suppressed the formation of the barium precursor and refluxed at 80 °C. The filtered sols were then spin-coated onto different substrates and cured at different temperatures in air. The BaTiO3 thin films prepared from two

What happens if a barium precursor dissolves faster than a titanium precursor?

(1) When the barium precursor dissolves faster than the titanium precursor (upper panel in Figure 23), BaCO3 dissociates and dissolves in the molten salt upon further heating. It then coats the TiO2 nanostructures forming the shell. The barium precursors then react with the TiO2 to form BaTiO3 rods.
