Natural mineral sources are necessary to make commercially usable calcium carbonate. Manufacturing processes are used to improve specific properties and reduce the size of particles within the material. Calcium carbonate is mined from open pits or underground, then drilled, blasted, and …
In the present paper, precipitated calcium carbonate (PCC) has been produced from waste marble powder (WMP) by the Calcination-Dissolution-Precipitation (CDP) method.
In this study, the Ca/P ratio and carbonate contents of the HAp crystals were slightly increased with increasing the processing temperature. The carbonate content affects to Ca/P ratio of HAp crystals. Using a calcium carbonate as a starting materials for HAp preparation under a hydrothermal condition, carbonate is generated by its dissolution.
Calcium carbonate decomposes under well-defined conditions giving CaO (solid) and CO2 (gas). The process kinetics are known to be strongly influenced by the CO2 partial pressure and temperature. In dynamic conditions, as in thermogravimetric analysis (TG) and differential thermal analysis (DTA), kinetics influence the observed …

Calcium as a nutrient is most commonly associated with the formation and metabolism of bone. Over 99 percent of total body calcium is found as calcium hydroxyapatite (Ca10[PO4]6[OH]2) in bones and teeth, where it provides hard tissue with its strength. Calcium in the circulatory system, extracellular fluid, muscle, and other tissues is critical …
From wikipedia article of calcium oxide. Calcium oxide is usually made by the thermal decomposition of materials, such as limestone or seashells, that contain calcium carbonate ($ce{CaCO3}$; mineral calcite) in a lime kiln.
