Abstract Ceramic material is a commonly used material with high mechanical properties such as high hardness, high wear resistance, corrosion resistance and high temperature resistance. It has been processed into various complex structures and applied to the field of industrial and agricultural production.. Since the process of ceramic products is susceptible to factors such as mixing and sintering, it is easy to cause internal or external defects of ceramic products, and the defects of ceramic products are relatively small and difficult to be recognized by human eyes. If the defects existing in ceramic products cannot be detected in time and effectively, they may have a serious impact on the application of subsequent products. In order to solve this problem, this paper analyzed and discussed the application status and existing problems of existing non-destructive testing methods from the perspective of non-destructive testing of ceramic products, and discussed the key technologies and development trends of non-destructive testing of ceramic products.
