用玻璃态前体生产多晶相，即，微晶玻璃加工，具有制造复杂材料的巨大潜力。本研究制备了Bi_2O_3-Fe_2O_3-BaO-B_2 O_3系统前驱体，其中BiFeO_3相是可结晶的，并研究了所得玻璃陶瓷的相形成和物理性能。在由BiFeO_3相组成的微晶玻璃中发现了铁电性和铁磁性，多铁性微晶玻璃本研究为BiFeO 3多晶材料的合成提供了一种新的方法。
A production of polycrystalline phase with glassy precursor, i.e., glass-ceramics processing, has a great potential to fabricate the sophisticated materials. In this study, we have prepared the Bi2O3–Fe2O3–BaO–B2O3 system precursor, in which BiFeO3 phase is crystallizable, and examined the phase formation and physical properties in resulting glass-ceramics. We found both ferroelectricity and ferromagnetism in the glass-ceramics consisting of BiFeO3 phase, i.e., multiferroic glass-ceramics. This study has demonstrated an alternative method for synthesis of polycrystalline BiFeO3 material.
