Definition of Calcium - MedicineNet
Calcium: A mineral found mainly in the hard part of bones, where it is stored. Calcium is added to bone by cells called osteoblasts and removed from bone by cells called osteoclasts. Calcium is essential for healthy bones and is also important for muscle contraction, heart action, and normal blood clotting.
Neither the metal nor the oxide was available in pure form until ion exchange separation and metallographic reduction techniques were developed by Spedding and associates in 1950. Physical Appearance: Dysprosium is bright silver in color.

Metal Foams – Properties, Production and Appliions
About 1.5 wt.% calcium metal is added to an aluminium melt at 680 C (1256F ). The melt is mixed well and the viscosity starts to increase due to the formation of calcium oxide, calcium aluminum oxide, or Al 4 Ca intermetallics. This aids in thickening of the
CHAPTER 2 - PRODUCTION, PROPERTIES AND USES OF …
This is done by using a calcium salt with a low solubility (such as calcium citrate) which slowly releases calcium ions. An alternate method is to use a calcium salt which is practically insoluble in neutral solution but dissolves as the pH falls (such as dicalcium phosphate); when an acid of low solubility (such as adipic acid) is added, it gradually lowers the pH, calcium ions are released
EP0948569A1 - Method of suspending insoluble calcium …
The process includes blending the insoluble calcium salt with an agitated aqueous mixture of a protein source, either soluble or insoluble, followed by drying the resulting mixture. The resulting dry powder can be reconstituted in water or other media to produce a suspension of the insoluble calcium salts with the beneficial feature that the calcium salts do not sediment or separate.
