The Effect of Temperature Synthesis on the Plate-Like Particle of Bi4Ti3O12 Obtained by Single Molten NaCl Salt

Three-layer Aurivillius compound bismuth titanate (Bi 4 Ti 3 O 12 ) is well known for having interesting properties such as ferroelectric and photocatalyst. Many researchers reported that the unique plate-like shaped particle affecting ferroelectric and photocatalyst properties. The molten salt synthesis is the common simple method to obtain that unique morphology. In this research, Bi 4 Ti 3 O 12 was synthesized using single molten salt NaCl at various temperatures, which is 800, 850, 900, and 950 o C. X-Ray Diffraction data showed that all obtained Bi 4 Ti 3 O 12 have a B2 cb space group with no impurities detected. The Raman spectra shows the characteristic vibration modes of Bi 4 Ti 3 O 12 at 62, 117, 228, 269, 332, 364, 536, 851 cm -1 . The plate-like shaped particle was confirmed by SEM analysis. Based on SEM images, the size of the particle increased along with the synthesis temperature, which is due to the thermal effect on grain growth.
