Calcium is a vital element in the periodic table, known for its significance in biological processes as well as its widespread use in various industries

Physical Characteristics:

  • Symbol: Ca
  • Atomic Number: 20
  • Atomic Mass: 40.078 u
  • Category: Alkaline Earth Metal
  • State at Room Temperature: Solid
  • Color: Silvery-white metallic
  • Density: 1.55 g/cm³ (at 20°C)
  • Melting Point: 842°C (1548°F)

Applications:

  1. Construction Material: Calcium is a key component in cement and lime (calcium oxide, CaO), crucial for the construction industry in making concrete and mortar.
  2. Metallurgical Processes: Calcium is used as a reducing agent in the extraction of other metals, such as uranium, zirconium, and thorium. It’s also used to deoxidize, desulfurize, and decarburize alloy steels to improve their workability and mechanical properties.
  3. Dietary Supplement: As an essential element for biological organisms, calcium supplements are used to prevent and treat calcium deficiencies. It is crucial for bone and teeth formation, blood clotting, and muscle function.
  4. Agriculture: Calcium compounds, such as calcium nitrate and lime, are used to enrich and stabilize soil acidity, providing essential nutrients to plants.

 Compounds:

  1. Calcium Carbonate (CaCO3): Found in limestone, chalk, and marble, it’s used in construction, as a filler in paper, plastics, and paint, and is the main component of agricultural lime.
  2. Calcium Oxide (CaO), Lime: Used in the production of cement, as a desiccant, and in various industrial processes requiring a strong base.
  3. Calcium Hydroxide (Ca(OH)2), Slaked Lime: Utilized in water treatment, soil stabilization, and as a key ingredient in mortars and plasters.
  4. Calcium Sulfate (CaSO4), Gypsum: Employed in the manufacture of plaster of Paris and drywall; also used as a soil conditioner.
