A metallic element (specific gravity 1.55 g/cm3), calcium is the fifth most abundant metal in the Earth’s crust. It is essential to human health and can be found in milk, cheese, leafy green vegetables, and nuts.
A vital nutrient for all living things, calcium is essential to the growth of healthy bones and teeth. It also helps muscles move by carrying signals from the brain to other cells, and it is necessary for many metabolic processes in the body.
Calcium is used to make white paint, cleaning powder, toothpaste and stomach antacids. It is also the primary component of limestone, marble, and chalk.
The element’s compounds are widespread, including calcined calcium carbonate (CaCO3) and gypsum (CaSO4). Gypsum, often called “plaster of Paris,” is used by builders and nurses to set fractured bones.
As an alkaline earth metal, calcium plays an important role in controlling soil pH (potential of hydrogen), a measure of the acidity or alkalinity of the soil. Problems can arise when a soil has too much or too little calcium, which affects the ability of plant growth and soil decomposition.
Calcium has a low reactivity with air, but it can be extremely hazardous when mixed with water or other acids. It can also be very dangerous when swallowed or inhaled.
Calcium is widely used to manufacture a variety of products, including acetylene (carbon-based fuel), hydroxyl (solvents) and organic solvents. It is also a key chemical in the manufacturing of electrical insulators, cathode materials and steel-deoxidizing agents. It is also a valuable source of rare-earth metals.
