Materium is specialized in silica-based additives – Amorphous silica. Their high specific area and custom functionalization make them excellent adsorbents for different chemical and biological pollutants present in water and air (filtration/purifications applications). Our hollow silica microsphere offer a media support for microorganism growth which can be used as bacterial carriers for both aerobic and anaerobic conditions for waste water treatment & Bio-Application. They could act as a weight-reducing fillers for polymers. – Silica-graphene composite having remarkable specific area and excellent adsorption properties for applications in water and gas purification. This results in a low density material having remarkable specific area and thermal and/or electrical conductivity due to the presence of graphene. – Graphene flakes for adsorption applications, they can be functionalized with various polar or non-polar molecules. Nnanoflakes of graphene or graphene oxide available in solution or in the form of powder. The size of these flakes ranges from 1-20 μm with a thickness of several nanometers (few layers of graphene or graphene oxide). – Microcapsules: Services of active agent encapsulation for cosmetics, textile, microelectronics, advanced material, bioapplication.
