Abstract

The article analyses the processes which take place in ceramic samples during their freezing and thawing. The
deformation parameters change is connected with the structure of ceramic samples and the processes of filling the
porous volume with water. Before unilateral cyclic freezing and thawing the porous volume of ceramic products must be
partly filled for allowing the migration processes to take place. The destruction of ceramic products is a complicated
process and it consists of three stages.
