As the application of MLCC has been extended to many fields, MLCC is required to have stable performance at high working temperature as well as in a wide temperature range. So temperature-stable MLCC dielectrics are urgently needed. BaTiO3 based materials exhibit advantages such as high permittivity, low dielectric loss, low cost and being environmentally-friendly, which make it one of the most widely studied candidates for MLCC dielectrics. However, the permittivity-temperature stability of purified BaTiO3 is unable to meet the requirement of temperature-stable MLCC. Owing to the limitation of the Curie tempe-rature of BaTiO3, it is hard to improve its permittivity-temperature stability to achieve the X8R/X9R standard by simply modifying BaTiO3 itself. Therefore, the avenue of forming BaTiO3-based solid solutions with the mixture of other perovskite compounds including Bi(M)O3, (Bi0.5Na0.5)-TiO3, K0.5Na0.5NbO3 and CaCu3Ti4O12 has attracted much attention, as well as the modification of received BaTiO3-based complex perovskite dielectrics. In this paper, the research progress on BaTiO3-based complex perovskite dielectrics for temperature-stable MLCC application in recent years is reviewed, and the development prospects are commented.
