Computer simulations indicate calcium carbonate has a dense liquid phase
Computer simulations could help scientists make sense of a recently observed and puzzling wrinkle in one of nature's most important chemical processes. It turns out that calcium carbonate -- the ubiquitous compound that is a major component of seashells, limestone, concrete, antacids and myriad other substances -- may momentarily exist in liquid form as it crystallizes from solution. Calcium carbonate is a huge player in the planet's carbon cycle, so any new insight into how it behaves is potentially big news.
