Ceramic elastostiff and elastoplastic semipermeable membranes

The results of obtaining ceramic elastic-rigid and elastic-elastic capillary-porous structures are presented and the possibility of their modification into thin-layer semipermeable membranes with filtration properties is investigated. It has been established that the most effective technological methods for the manufacture of ceramic membranes based on spondyloid clay and calcium-phosphate materials are semi-dry multistage pressing of initial powders and casting from suspensions. A comparative study of elastic-rigid membranes of two main compositions was carried out, the presence of a capillary-porous structure and the proximity of the values ??of their gas permeability and filtration rate were established. The study of elastoelastic resorbable and semi-resorbable membranes based on biogenic hydroxyapatite showed that they are promising for use in medicine. Tab. 2, bibliography: 6 titles.
