Conclusions
The effectiveness of the method of AE for controlling the defectiveness of the structure and nondestructive evaluation of the strength of ceramics and refractories depends on the specific features of their deformation which can be taken into account on the basis of the characteristic structure-sensitive brittleness index of the materials. In this case, the method of AE can be most effectively used for relatively brittle ceramic materials. When using this method for testing brittle ceramics, in most cases, it is possible to distinguish only the specimens containing large structural defects that control their strength.
