How Thermal Analysis can unlock Nature’s Secrets

Amorphous calcium carbonate (ACC) is the amorphous and least stable polymorph of calcium carbonate. ACC is extremely unstable under normal conditions and is found for example in sea urchins and corals. The influence of ACC on the outstanding macromechanical properties of Echinoderm calcite is unknown. In this paper Thermal Analysis methods were used to investigate the thermal stability of sea urchin spines.
