摘要

Ba_0.6Sr_0.4TiO₃-MgTiO₃ composites were prepared by reaction of BST powders with molten MgCl₂ at various MgCl₂/BST molar ratios at 600 and 800 °C in air. The products were examined by X-ray diffraction (XRD) and scanning electron microscopy (SEM). It is shown that the ceramic composites have a relaxor-like ferroelectric transition as MgTiO₃ is above 8 mol%. The addition of MgTiO₃ has greatly reduced the dielectric loss of BST ceramics. The BST-MT ceramics could be a promising candidate for tunable microwave device applications.
