S11: Geopolymers – Low Energy, Environmentally Friendly, Inorganic Polymeric Ceramics



Geopolymers are inorganic polymers formed from naturally occurring aluminosilicates by reaction with concentrated alkali solutions at near ambient temperatures. Other inorganic polymers include phosphates. Recent research has revealed the versatility of these materials for many applications, such as fire resistant panels, acid and brine resistant materials, biomaterials, electronic materials, materials forĀ  immobilizing/encapsulation of hazardous metal ions and low and intermediate level nuclear waste. They can be used in construction applications where ceramics and Portland cement are used. In fact the potential to produce new materials with applications even not thought of at present is enormous. In this symposium some of these new developments will be examined and explored.


Proposed Symposium Topics

  • Synthesis and properties of novel aluminosilicate and phosphate geopolymers
  • Sintering kinetics and aluminosilicate precursors
  • Processing of geopolymers including heat-treatment
  • Microstructure and mechanical properties
  • Application of spectroscopic techniques for advanced study
  • Encapsulation and Hazardous Waste Immobilization
  • Applications where ceramics and cement are currently used
  • New applications
