The article considers the processes leading to a change in the structure and properties as a result of thermal treatment of natural zeolites from the Rkoni plot of the Tedzami deposit, Georgia, containing up to 80% of heulandite and 10% of chabazite, from the Chankanay deposit, Kazakhstan, containing up to 70% of heulandite-chabazite mixture, and from the Nor Kokhb deposit, Armenia, containing over 80% of clinoptilolite, selected for the creation of new bactericidal zeolite filter materials for purification and desinfection of water from various sources. The thermal stability of the samples is determined, the parameters of dehydration, amorphization and the effect of heat treatment on micro- and mesoporous systems of zeolites are established.
