The results of studies on the preparation of porous glass-crystalline materials with a permeable structure by the method of directional crystallization of a complex of phases are presented. The phase composition of materials has been studied using the methods of X-ray phase, X-ray fluorescence and electron microscopic analysis, and the features of their microstructure have been investigated. The prospects of using the synthesized materials as filters for the purification of various media have been established. Tab. 1, ill. 2, bibliography: 4 titles.
