Abstract
A mechanism of formation of a permeable ceramic structure based on a granular filler and a fine-grained sintering binder is proposed. It is observed that the finely dispersed component lowers the permeability of the structure. The impossibility of obtaining a granular permeable structure in the case of using a binder made of reaction-sintered silicon nitride is demonstrated. Permeable ceramics is produced from granulated powder, which makes it possible to avoid the fine-grained component in the volume of permeable channel-shaped pores.
