carbonation A chemical
weathering process in which dilute carbonic acid, derived from the solution in water of free atmospheric and soil-air carbon dioxide, reacts with a mineral. The best-known example is the reaction between limestone (calcium carbonate) and carbonated water (carbonic acid) which yields calcium and bicarbonate ions in solution:CaCO
3 + H
+ + HCO
−3 → Ca

Carbon-based insulation keeps it cool when it's really hot: when talking about temperature, high is a relative term. When things get really hot (above 1830[degrees]F), however, cost versus performance analysis reveals the value of carbon-based insulation materials. Because of their unique carbon content and structure, they lend themselves well to providing the required thermal protection at extremely high temperatures.(Ceramics & Refractories/Insulation)
