Biomimetic Calcium Phosphates Derived from Marine and Land

Dec 20, 2017· Regardless of the CaCO 3 polymorphic form (aragonite, calcite or dolomite), thermal dissociation takes place through calcination at temperature of 800–1200°C, for at least 2 hours [5, 6, 16, 17, 34]. Calcination leads to carbon dioxide (CO 2) release, associated with a mass loss of ~45%.
