Lead-free (1-x)Bi0.5Na0.5TiO3-xCaSnO3 ceramics with high thermal stability
Source abstract
Abstract
High-temperature ceramic capacitors has become an important research topic with the upgrading and development of emerging industries such as electronic information. In this study, a series of lead-free (1- x)Bi 0.5Na 0.5TiO 3- xCaSnO 3 (BNT- x CS) ceramics with good temperature stability were designed and synthesized using a solid-state reaction method. The temperature stability were improved with the addition of CS, which is closely related to the suppression of the ferroelectricity of BNT ceramics. Remarkably, BNT-0.15CS ceramic displayed a superior temperature stability of Δε/ε 150 °C ≤ ± 15% in the range of − 96 ∼ 500 °C, as well as a low dielectric loss tanδ = 0.003 at 150 °C (1 kHz). The finding in this work not only explores how to improve the temperature stability of BNT and related materials, but also provides candidate materials for high-temperature ceramic capacitors.
