Abstract:

Barium strontium titanate (Ba1-x Sr x TiO3,BST) ceramics, as an environmentally friendly ferroelectric material, have attracted considerable attention among lead-free dielectric tunable materials due to their excellent dielectric properties, large dielectric nonlinearity, good chemical stability, and adjustable Curie temperature. Owing to simple preparation processes and relatively low production costs, BST ceramics exhibit wide application prospects in modern communication systems, electronic information equipment, and tunable microwave devices. In recent years, extensive research on the enhancement of tunable properties and comprehensive improvement of dielectric characteristics in BST ceramics has been carried out, aiming to meet the requirements of next-generation tunable microwave devices. This work systematically review the research progress and current status of tunable properties in BST ceramics from the three key aspects: the doping modification, the design of multi-phase composites, and the optimization of the preparation process. Furthermore, a valuable reference for the future development and application of high-performance dielectric tunable materials is provided.
