Abstract
A high temperature composite includes a binder, cement or geopolymer and ceramic filler, negative coefficient of thermal expansion materials of AM2O8 or A2(MO4)3 family or ZrV2O7. The material is compatible with concrete, any ceramics or metals or metal alloy. The material is heat shock resistant and stable in harsh chemical environments and is impermeable to most solvents. The new sealant materials can be used as sealants, heat shock resistant structural materials and coatings.
