Abstract
With growing concern on health and safety worldwide, a requirement for environmentally benign piezoelectrics are continually increasing. The Bi0.5Na0.5TiO3 (BNT) ceramic is a promising piezoelectric material without the lethal element, Lead. Conventional mixed oxide method generally yields BNT with grains in the micron range. Nanocrystalline materials could be obtained by chemical route but at high expense. Reaction of Bi2Ti4O11 with excessive Na2CO3, has been found to produce nanocrystalline BNT at low temperature. SEM showed recrystallization of BNT. Crystallize size calculation from X-ray diffraction confirmed that the size of the crystals were in nanometer range. (c) 2005 Elsevier Ltd. All rights reserved.
