Thermogravimetry/Differential Thermal Analysis and Phase Identification of Cs2O·Al2O3·2TiO2 in the Ternary System Cs2O-A12O3-TiO2

Thermogravimetry and differential thermal analyses were conducted on the mixture 2CsNO3+A12O3+2TiO2 up to 1530 K. The resultant phase was identified as orthorhombic Cs2Al2Ti2O8 with lattice parameters aO=0.996, b0=0.898, and co=0.573 nm. Simultaneous TG/DTA was performed to quantify weight loss and volatilization of cesium and to monitor the development and/or stability of the phase as a function of temperature.
