An inorganic room-temperature setting material for the encapsulation of waste. These materials are a class of chemically bonded ceramics that are manufactured at lower temperatures like typical hydraulic cements, but perform much more like high-temperature fused ceramics. The name derives from the low-temperature reduction/oxidation reactions by which the material is bound. These materials are formed by a combination of ionic, covalent, and van der Waals bonding, with the stronger ionic and covalent bonds dominating. Chemically bonded ceramics are much stronger than typical room-temperature hydraulic cements that are formed by comparatively weaker van der Waals and hydrogen bonding.
