摘　　要：综述了目前YIG(Y3Fe5O12)多晶铁氧体材料在低温烧结方面的研究现状。总结了Cu、Ca、V、Bi等离子取代及TiO2、B2O3添加剂对YIG显微结构及磁性能的影响,探讨了用sol-gel法、共沉淀法及机械化学法制备的YIG超细粉料在低温烧结中的作用以及新型烧结工艺的应用。阐述了其未来的研究方向。The present situation in research of the low-temperature sintering for YIG（Y3Fe5O12） is summarized. The influences of Cu, Ca, V, Bi etc ion substitutions and TiO2, B2O3 additives on the microstructure and the magnetic properties of YIG are described. Furthermore, the effect of ultrafine YIG powders prepared from sol-gel, co-precipitation and mechanochemical methods on the sintering behavior as well as the application of a new sintering technique are explored. Lastly, the development tendency of low-temperature sintering of YIG polycrystialline ferrite is also mentioned.
