研究了快淬法制备的非晶Bi_4Ti_3O_（12）样品的晶化过程。差热分析、粉末X射线衍射和拉曼光谱测量表明，非晶样品首先在约610°C下结晶成亚稳Bi2Ti2O7相，然后在约830°C下不可逆地转变成稳定的Bi4Ti3O12相。
We studied the crystallization of amorphous samples of Bi4Ti3O12 prepared by rapid quenching. Differential thermal analysis, powder X-ray diffraction and Raman spectral measurements revealed that the amorphous sample first crystallizes at approximately 610°C to a metastable Bi2Ti2O7 phase and then transforms irreversibly to the stable Bi4Ti3O12 phase at approximately 830°C.
