Sol-gel synthesis and characterization of BaTi2O5 powders

BaTi2O5 powders were synthesized using a sol-gel method and characterized. Phase evolution and characteristics of the samples were studied using differential scanning calorimetry, thermogravimetric analysis and X-ray diffractometry. The results show that the formation of BaTi2O5 starts around 800 °C...

BaTi2O5 powders were synthesized using a sol-gel method and characterized. Phase evolution and characteristics of the samples were studied using differential scanning calorimetry, thermogravimetric analysis and X-ray diffractometry. The results show that the formation of BaTi2O5 starts around 800 °C and continues until 1200 °C in air, and in this calcination temperature range all powders appear to be single-phase monoclinic BaTi2O5.
