calcium | Definition, Properties, & Compounds | Britannica
Calcium constitutes 3.64 percent of Earth’s crust and 8 percent of the Moon’s crust, and its cosmic abundance is estimated at 4.9 × 10 4 atoms (on a scale where the abundance of silicon is 10 6 atoms). As calcite (calcium carbonate), it occurs on Earth in limestone, chalk, marble, dolomite, eggshells, pearls, coral, stalactites, stalagmites, and the shells of many marine animals.
Calcium is a mineral that is crucial for proper formation of strong bones and teeth. It also plays a vital role in maintaining regular heartbeat and the proper transmission of nerve impulses.Calcium stores determine the effect peristaltic action of the intestines and the health of muscle fiber..

New chemistries found for liquid batteries | MIT News
22/3/2016· First, the researchers tackled the temperature problem by alloying the calcium with another inexpensive metal, magnesium, which has a much lower melting point. The resulting mix provides a lower operating temperature — about 300 degrees less than that of pure calcium — while still keeping the high-voltage advantage of the calcium.
