使用差热分析(DTA)装置测定Bi2O3-TiO2相图。通过助熔剂法生长的 Bi4Ti3O12 (BIT) 云母单晶透明，颜色略带灰色。通过测量电位移与电场磁滞回线和介电常数来观察 BIT 晶体的铁电和介电特性。此外，还研究了BIT晶体的偏振切换特性。从瞬态波形中读取开关时间和开关电流密度。
A Bi2O3-TiO2 phase diagram was determined using differential thermal analysis (DTA) apparatus. Bi4Ti3O12 (BIT) micalike single crystals grown by a flux method were clear and slightly grayish in color. Ferroelectric and dielectric properties of BIT crystals were observed from measurements of electric displacement vs electric field hysteresis loops and the dielectric constant. Also, the polarization switching characteristics of BIT crystals were investigated. The switching time and switching current density were read from the transient waveforms.
