Abstract
Geopolymer composite materials having low coefficient of thermal expansion are disclosed. The materials are useful in high temperature applications due to their low coefficient of thermal expansion and high strength. Also disclosed is a boron modified water glass geopolymer composition that is compatible with ceramic particulate material such as cordierite and fused silica. The geopolymer composite may be extruded to form structures such as honeycomb monoliths, flow filters or used as a plugging or skinning cement and may be fired at temperatures at or below 1100° C. Both the structures and the cement have high green and fired strength, a low coefficient of thermal expansion, and good acid durability. The cost of manufacturing objects using the material of the present invention is substantially reduced, in comparison with typically production methods of cordierite based bodies, due to the substantially shortened firing times.
