Abstract

On the base of mixtures kaolin (or bentonite) - ground fusible glass - polyurethane sponges in the temperature range 800 - 900 deg C porous ceramics were obtained. The low-temperature synthesis of ceramics is based on the stage-by-stage formation of low-temperature eutectics between feldspar, silica, and newly formed products of interaction between glass melt and aluminum silicates. The investigation of absorptive, adsorptive and filtration properties of such ceramic materials gives possibility to recommend theirs for filtration (separation) of crude oil and toxins from water mixtures and emulsions, absorption of toxins and dyes from water solutions.
