摘要：
Processes accompanying creep in ceramics and refractories are considered. Structural defects can be ranked according to their effect on creep (in descending order): macropores; low-melting phase inclusions, especially of vitreous phase; micropores; crystal boundaries, especially passing via micropores; block boundaries, dislocations; vacancies. The sequence is determined by intensity of diffusion mass transfer, i.e., the concentration of vacancies near the structural elements (defects) listed.
