摘　　要：采用了一种新的电场辅助化学溶液工艺技术制备了硅酸锂(Li2SiO3)陶瓷薄膜。结果表明,这种方法可在较低的温度下获得成分单一的硅酸锂(Li2SiO3)陶瓷薄膜。利用X射线衍射技术(XRD)对薄膜的晶体结构进行了表征;利用扫描电子显微技术(SEM)观察了薄膜的表面形貌;并对硅酸锂(Li2SiO3)陶瓷薄膜的制备过程进行了详细的分析和讨论。Mono-phase lithium silicate （Li2SiO3） ceramic films have been directly fabricated on a conductive substrate by a developed electric field associated chemical solution process at low temperature. The crystal structure and the surface morphology of the ceramic films were characterized by X-ray diffraction （XRD） and scanning electron microscopy （SEM） techniques respectively. And the preparing processes for the lithium silicate （Li2SiO3） ceramic films are described and discussed. Comparing with the conventional lithium metasilicate fabrication techniques, the technique in present work is a component-controllable and low temperature synthesizing processing.
