Abstract:

Barium titanate?based electronic ceramic materials are widely used in capacitors,integrated circuits,sensors,thermistors and other fields.Industrial requirements such as capacity,miniaturization,breakdown resistance,and low loss put forward higher requirements for the performance of barium titanate?based electronic ceramic materials.Modification is the main mean to improve the performance of ceramic materials.The research progress on barium titanate?based electronic ceramic materials in doping modification,composite modification and physical modification in recent years was reviewed.The problems in the modification of barium titanate based electronic ceramics,such as insufficient optimization of preparation parameters of conventional elements,fewer types of rare earth elements,cladding effect to be improved,poor comprehensive performance of polymer ceramic composites,and sintering process to be optimized were analyzed.Solutions were proposed,such as exploring multiple element doping,optimizing process parameters,improving coating and polymerization methods,etc.The future development direction of barium titanate based electronic ceramic materials was pointed out.It was strengthening research of the mechanism of grain size,crystal shape and component regulation in the sintering process,selecting more rare earth elements for modification,and exploring new processes such as coating doping modification and polymer composite modification.
