Abstract

The invention provides a lead-free electronic ceramic material with low dielectric loss in wide working temperature area. The chemical formula is Na1+xBiTi6O14+0.5x, where x is equal to -0.02 to 0.02.The invention also provides a preparation method of the lead-free electronic ceramic material. According to the lead-free electronic ceramic material, the content of Na is changed, the dielectric temperature stability of the ceramic is improved, the minimum dielectric loss of the ceramic is reduced, and the ceramic sheets with different properties are obtained, so that the lead-free electronic ceramic material can be applied to the ceramic capacitor pieces with different performance requirements, and the application range is wide.

Description

technical field [0001] The invention belongs to the technical field of preparation of electronic ceramic components in information functional materials, and in particular relates to a lead-free electronic ceramic material with a wide working temperature range and low dielectric loss and a preparation method thereof. Background technique [0002] Dielectric materials are an important basis for the further development of important electronic devices such as capacitors, memories, resonators, and filters to high performance and miniaturization. Due to the application needs of device miniaturization and high energy density storage, the exploration of dielectric materials has become a hot spot in the field of new material research at home and abroad in recent years. However, it is still an extremely challenging task to realize the excellent comprehensive dielectric properties of dielectricity, low loss, operating frequency bandwidth, temperature stability, and strong electric fiel...
