摘要：
The single-crystalline Bi3.25La0.75Ti3O12 Micro-platelets were directly synthesized in the NaCl-KCl medium at the relative low temperature by means of molten salt synthesis method (MSS). The as-prepared Bi3.25La0.75Ti3O12 solid solution exhibits the monoclinic symmetry (P1a1) which was revealed by the X-ray and electron diffractions. In the NaCl-KCl medium, the square platelet of single-crystal Bi3.25La0.75Ti3O12 grew along its crystal habit plane (001), and its thickness increased layer by layer. The growth mechanism could be that it was an edge nucleation, grew in amorphous as early stage, and then preferentially crystallized along (001) plane. (C) 2007 Elsevier B.V. All rights reserved.
