This paper describes and discusses the application of the original sintering process named cold sintering to the electrolyte material BaCe_0.8Zr_0.1Y_0.1O_3-δ to enhance its densification at a temperature below that needed in a conventional sintering. This new technique enables the acceleration of the densification resulting in a more compacted microstructure with an unexpected high relative density of 83 % at only 180 °C. A subsequent annealing at 1200 °C further enhances the densification which reaches 94 %. The electrochemical performance of CSP sintered ceramics was investigated and optimized by varying different process parameters. The comparison with the conventional sintered material reveals an increase of the total conductivity by mostly increasing the grain boundary one. This result emphasizes the benefits of CSP to not only reduce the sintering temperature but also to enhance the electrochemical properties.

本文描述并讨论了原始烧结工艺冷烧结在电解质材料BaCe _0.8 Zr _0.1 Y _0.1 O3 _{-δ中的应用}以在低于常规烧结所需温度的温度下提高其致密性。这项新技术可以加速致密化过程，从而使组织更加致密，仅在180°C时，出乎意料的相对密度高达83％。随后在1200°C进行的退火进一步增强了密度，达到94％。通过改变不同的工艺参数，对CSP烧结陶瓷的电化学性能进行了研究和优化。与常规烧结材料的比较表明，通过主要增加晶界之一，总电导率得以提高。该结果强调了CSP的益处，其不仅降低了烧结温度，而且还增强了电化学性能。
