On the basis of model and experimental studies, the formation of the structure of a porous highly refractory ceramic material with a granular structure has been studied. The concept of the structure of the ceramic material of rods as a material consisting of interpenetrating bulk clusters of oxide grains of various sizes cemented with a ceramic bond has been developed. Using the main provisions of the percolation theory, a study of a model structure with cubic packing was carried out and a correlation was established between the structure-sensitive shrinkage phenomena of the ceramic material of the rods and the fraction of nodes belonging to the skeleton of an infinite cluster
