Sintering of Silica-Alumina Granular Materials and its Catalytic Properties

Abstract

In this work was developed a filtering material, where a granular glass-ceramic with a catalytically active layer applied as a carrier. The main component of the pellet batch is alkaline glass which made it possible to intensify the processes of melting and foaming of the molten glass. It has been defined physical and technical characteristic of granules and obtained that its density smaller 300 kg/m3 and strength under compression layers between 0.8-2.6 MPa. Taking into account the physical and technical characteristics of GCM granules, studies were carried out to determine the possibility of using them as filtering media with a catalytically active layer. This makes it possible not only to dispose of cullet, but also to create a highly efficient material from it, allowing water to be purified up to standards.
