Notes:
Bismuth titanate nanopowders were prepared by the hydrothermal method fromBi(NO3)3·5H2O, TiCl4 and KOH aqueous solution. The influences of reaction temperature and KOHconcentration on the crystalline phase, morphology, and grain size of the prepared Bi4Ti3O12 powderswere investigated. The results showed that well-crystallized, dispersive Bi4Ti3O12 nanopowders couldbe prepared by the hydrothermal treatment at 220–260[removed info]˚C for 6 h, in the case of [Ti]= 0.1 M, Bi:Ti =4:3 and [KOH]=1.0–2.0 M. The prepared Bi4Ti3O12 powders of the orthorhombic structure wereobserved to be rectangle slice-shaped, and the grain sizes were about 30 nm in width and above100nm in length. It was also confirmed that the desired concentration of KOH decreased with increasingof the treatment temperature
