Symposium 16: Geopolymers: Low-Energy and Environmental-Friendly Ceramics



Ceramic-like inorganic polymers can be made under low-energy conditions, such as ambient temperatures and pressures. These materials include aluminosilicates or “geopolymers,” phosphates, and other chemically bonded inorganic compounds. The use of waste products or natural materials as starting compounds or as reinforcements in composites demonstrates the ecofriendly and sustainable nature of these materials. Novel potential applications of such composites include hydrogen storage, water purification and biocidal activity, porous materials for CO2 sequestration, thermal insulation, fire-resistant building materials, and structural ceramic composites.
