OBSERVATION OF CRYSTALLIZATION PROCESS FROM AMORPHOUS Bi4Ti3O12 PREPARED BY RAPID QUENCHING METHOD

Authors studied the crystallization of amorphous samples of Bi4Ti3O12 prepared by rapid quenching. Differential thermal analysis, powder XRD and Raman spectral measurements revealed that the amorphous sample first crystallizes at approx 610 C to a metastable Bi2Ti2O7 phase and then transforms irreve...

Description
Summary:Authors studied the crystallization of amorphous samples of Bi4Ti3O12 prepared by rapid quenching. Differential thermal analysis, powder XRD and Raman spectral measurements revealed that the amorphous sample first crystallizes at approx 610 C to a metastable Bi2Ti2O7 phase and then transforms irreversibly to the stable Bi4Ti3O12 phase at approx 830 C. 8 refs.
