首次测定了Na0.5Bi0.5TiO3单晶的室温弹性常数矩阵和C11常数（30 ~ 400℃）的温度依赖性。温度异常对应于铁电态的消失（~ 200°C），以及与介电常数最大值（~ 320°C）相关的宽最小约温异常。由此得出结论，这个最小值可能是动态效应，而不是结构相变的标志。此外，还指出了NBT在设备应用中的使用。
The elastic constant matrix at room temperature and the temperature dependence of C11 constant (30–400°C) of Na0.5Bi0.5TiO3 single crystal have been measured for the first time. The anomaly at the temperature, which corresponds to disappearing of ferroelectric state (∼200°C), and broad minimum about temperature, which correlates to maximum of electric permittivity (∼320°C), has been revealed. It has been concluded, that this minimum can be dynamic effect and does not indicate of the structural phase transition. Also the use of NBT for device applications has been indicated.
