Abstract This letter shows the chemical compatibility between LnZ and YSZ after heat treatment at high temperatures. It was found that LnZ would react with YSZ, and a reaction zone with relatively large grains formed after high temperature treatment, which would usually destroy the structural and compositional stability of the composite specimens. The reaction between LnZ and YSZ was caused by the element interdiffusion due to the chemical potential difference, and a higher sintering temperature would lead to a higher reaction rate. The common tangent law was used to analyze the phenomenon, and a solution was proposed to solve the issue.
