具有多铁性能的层状结构钛铁钴酸铋陶瓷材料及其制备方法
Abstract:
具有多铁性能的层状结构钛铁钴酸铋陶瓷材料及其制备方法，属于氧化物陶瓷材料制备技术领域，将Bi4Ti3O12和BiCoO3植入BiFeO3中形成Bi5Fe0.5Co0.5Ti3O15(BFCT)。该工艺简单合理，具有与现行的固相工艺良好的兼容性，样品制备温度远远低于现行工艺的制备温度可大大降低能耗，便于产业化生产。在BFCT中，由于Fe－O和Co－O八面体排列相对较为有序，从而局部获得Fe－O－Co之间的耦合，使样品的磁性高。
Abstract(English):

The invention relates to a multiferroic ferrotitanium bismuth cobaltates ceramic material with laminated structure and a preparation method thereof, which pertains to the technical field of oxide ceramic material preparation. Bi4Ti3O12 and BiCoO3 are implanted in BiFeO3 to generate Bi5Fe0.5Co0.5Ti3O15 (BFCT). The technology is simple and reasonable, and has good compatibility with current solid phase technology; the sample preparation temperature is far lower than that of current technology, thus greatly reducing energy consumption and facilitating industrialized production. In the BFCT, due to relative orderly arrangement of Fe-O and Co-O octahedron, local coupling of Fe-O-Co can be obtained, thus leading the magnetism of sample to be high.
