| 中文摘要 | The stability and phase transformations of the four BiB3O6 polymorphs, i.e., alpha-, beta-, gamma- and delta-BiB3O6, were investigated under different temperatures and pressures. beta-BiB3O6 is a metastable phase which can only be obtained by boric acid flux method in a sealed system at low temperature. The other polymorphs, alpha-, gamma- and delta-BiB3O6, are thermodynamic stable phases. Owing to the large kinetic effect, the phase transformations of the BiB3O6 polymorphs are generally slow, thus an extensive annealing process was used in this study. The study shows that alpha-BiB3O6 is the high-temperature phase and its stable area is narrow (710-715 degrees C) in atmospheric conditions, while gamma-BiB3O6 is a stable phase in the intermediate temperature range (similar to 680-710 degrees C). The results also confirm that delta-BiB3O6 is a high-pressure phase and all other polymorphs may transfer to delta-phase under high pressure. However, the delta-phase can be obtained by annealing alpha- or beta-BiB3O6 at relatively low temperature under ambient pressure. Therefore, delta-BiB3O6 can also be regarded as the low-temperature phase in this system. Based on the experimental results, as well as the thermodynamic principles, a pressure-temperature (P-T) phase diagram for the BiB3O6 system is proposed. |
