Soft Combustion Technique: Solution Combustion Synthesis and Low-Temperature Combustion Synthesis; to Prepare Bi4Ti3O12 Powders and Bulk Ceramics
Bi4Ti3O12 (BTO) powders were synthesized using soft combustion techniques, specifically known as Solution Combustion Synthesis (SCS) and Low-temperature Combustion Synthesis (LCS). XRD results showed that the single phase BTO was obtained following calcinations at 800oC for the sample prepared us...

Bi4Ti3O12 (BTO) powders were synthesized using soft combustion techniques,
specifically known as Solution Combustion Synthesis (SCS) and Low-temperature
Combustion Synthesis (LCS). XRD results showed that the single phase BTO was obtained
following calcinations at 800oC for the sample prepared using SCS; compared to after
combustion, for the sample prepared using LCS. The TG/DTA showed a combustion
temperature of around 252 - 280oC, which became stable with a single phase BTO at 500oC
and above. Sintering was carried out at 1,100oC for 3 h, to determine the microstructures,
grain orientation, relative density, dielectric, and ferroelectric properties, of the bulk
ceramics. It was found that the bulk ceramics prepared using SCS exhibited elongated-like
grains, strong (117)-preferred grain orientation, a relative density of 93.3%, εr = 320 - 360,
tan δ = 0.03 - 0.1, Pr = 6.8 μC/cm2, and Ec = 20 kV/cm. Meanwhile, the bulk ceramics
prepared using LCS showed plate-like grains, strong c-preferred grain orientation, a relative
density of 83%, εr = 143 - 195, tan δ = 0.01 - 0.38, Pr = 5.9 μC/cm2, and Ec = 30 kV/cm. |
