Problems solved by technology

However, the blocking electrode and the sample to be tested are connected together to form an electrochemical cell by co-sintering or direct contact under pressure, which will inevitably cause contact resistance, and at the same time, a certain The degree of electrode polarization phenomenon, while the current H-W method ignores the contact resistance and polarization interface resistance, resulting in inaccurate measurement results
Especially under high temperature conditions, when the resistance between the sample and the blocking electrode decreases, it will have a greater impact on the measurement results

Abstract

The invention discloses an ionic conductivity testing method for an ion-electron mixing conductor material. Based on the resistance variation caused by the measurement dimension range change of the ionic conductivity by measuring to-be-measured mixing conductor material after electron blocking, the ionic conductivity is obtained by calculating. In the testing process, the method is capable of avoiding the processing procedures caused by cutting materials, and preventing the loss of the materials in the processing process. The measurement error caused by the change of the material size can be avoided too. The testing method is simple and convenient, and the error is reduced in the greatest degree.

Description

technical field [0001] The invention relates to a method for testing the conductivity of a material, in particular to a method for measuring the conductivity of an ion-electronic mixed conductor material, which is applied to the technical field of functional conductive materials. Background technique [0002] A mixed conductor refers to a ceramic material that is capable of conducting both oxygen ions and electrons. At present, mixed conductors mainly include two-phase mixed conductors and single-phase mixed conductors. Two-phase mixed conductor is based on pure ionic conductor, by adding noble metal or electronically conductive oxide, it forms a continuous second phase in the material, and electrons and oxygen ions pass through different phases respectively; single-phase mixed conductor mainly It is a compound of perovskite and its derivative structure. Among them, the perovskite structure mixed conductor is made by doping low-valent metal element ions and transition meta...
