Photos Of Calcium
Hunk of solid Calcium
- Calcium compounds are most commonly found in sedimentary rocks such as limestone, chalk and marble where calcium carbonate minerals such as calcite and dolomite are present.
Particles of Calcium
- In powdered form, the reaction with water is extremely rapid and quite violent as the increased surface area of the powder accelerates the reaction.
Rock of Calcium
- Calcium compounds are used in the making of cement, glass, lime, bricks, paint, paper, sugar, removing non-metallic impurities from alloys, and as a reduction agent in the preparation of other metals.
Other Cool Facts
- Calcium is very important for the human body. 99% of the body's calcium is stored in the bones and teeth, helping to strengthen them. The other 1% helps with muscle movement allowing nerves to carry messages between the brain and our body parts. It helps blood vessels move blood around and assists with the release of hormones and enzymes. If you don't have calcium you can't live. The name calcium comes from the Latin word calx which means lime.
- Calcium is also found in other minerals such as gypsum (calcium sulfate) and fluorite (calcium fluoride) and it occurs to a lesser extent in igneous and metamorphic rocks, mainly in silicate minerals.
Uses of Calcium.
Calcium metal is used as a reducing agent in preparing other metals such as thorium and uranium, and as an alloying agent for aluminium, beryllium, copper, lead and magnesium alloys.
Calcium compounds are widely used.
