摘要
采用液相包覆法制备了MgO包覆的Ba0．6Sr0．4TiO3复合粉体。利用扫描电镜（SEM）和TEM观测了复合粉体前驱体的表面形貌，并用能谱仪（EDS）对前驱体表面进行了微区成分分析。在600℃煅烧合成了MgO包覆的Ba0．6Sr0．4TiO3（BSTO）复合粉体。液相包覆法制备的MgO-BSTO复合粉体包覆层较均匀，厚约为10～100nm。实验开创了制备纳米MgO包覆BSTO颗粒制备复合粉体的一种全新工艺。
Ba0.6Sr0.4TiO3-MgO composites were prepared by liquid-phase cladding process. The surface of the precursor was studied by SEM and TEM, and the composition of surface was analysed by EDS. The composites of Ba0.6Sr0.4TiO3 with MgO coating layer were obtained by calcining the precursor at 600 ℃, The layer of MgO-BSTO composites was regularly homogenous, with the thickness of 10-100 nm. A new technique of preparing MgO-BSTO composites was illustrated,
