Bi20TiO32 nanocones prepared from Bi–Ti–O mixture by metalorganic decomposition method
Bi20TiO32 in the form of nanocones are reported for the first time, which have been found
during the formation of Bi2Ti2O7 nanocrystals. Bi20TiO32 nanocones were prepared by
metalorganic decomposition technique. From X-ray patterns, it was found that Bi20TiO32 is
a metastable phase, and can transform gradually into Bi2Ti2O7 phase with the annealing
time increasing at a temperature of 550° C. The image of field emission scanning electron
microscopy shows that the lengths of the nanocones are up to several micrometers and the …
