Other common compounds of calcium include: calcium sulfate (CaSO 4 ), also known as gypsum, which is used to make dry wall and plaster of Paris, calcium nitrate (Ca(NO 3 ) 2 ), a naturally occurring fertilizer and calcium phosphate (Ca 3 (PO 4 ) 2 ), the main material found in

Calcium metabolism - Wikipedia

Calcium is one of the major ions in seawater. It is present in seawater at about 410 ppm the world over, so it comprises just under 1.2% by weight of the solids. Variations from this concentration are most often caused by changes in salinity, where the calcium goes up and down just as the salinity does.
