The tension creep rate of ceramic materials,
et·\mathop {\varepsilon t}\limits^ \bullet
, as a rule is higher than the compression creep rate
ec·\mathop {\varepsilon c}\limits^ \bullet
.

The magnitude of the ratio
et· /ec·\mathop {\varepsilon t}\limits^ \bullet /\mathop {\varepsilon c}\limits^ \bullet
depends mainly on the structure of the materials; the more complex and defective the structure the greater the
et· /ec·\mathop {\varepsilon t}\limits^ \bullet /\mathop {\varepsilon c}\limits^ \bullet
ratio.
