Diffusion and Filtration

Saint-Gobain Ceramics Materials has developped a range of porous media for industrial and laboratory diffusion and filtration processes of water, beverages and oil. 

 

Our Alundum® porous media are composed of fused alumina grains held together by a porcelain bond, therefore they are generally able to withstand temperatures up to 1000°C.
Our plates, tubes and disks can operate under high pressures, are resistant to breakage, chipping in handling and abrasion. They are not affected by corrosive - either acidic or alkaline - conditions found in most laboratory and industrial process.

Our Crystar® FT silicon carbide filters are very stable : they can filter corrosive and/or erosive liquids at high flow rates.

Porous media are classified on the basis of the rate of gas flow under a given set of conditions. This property is known as permeability. Porosity is defined as the percentage of volume of pores to the bulk volume of the piece. All our Alundum® porous media have a porosity of 35 to 4O%. The pore size and related number of pores are varied to produce the required permeability to suit the application. The uniform distribution of pores which is essential to the uniform passage of liquids and gases, is achieved through our controlled structure. This allows us to meet your grid specification requirements.
