Precautions
▶ Calcium carbonate is also used in industries like paint, plastic, rubber, ceramic, cement, glass, steel, oil refining, and in biorock creation for mariculture of sea organisms. ▶ The decomposition of calcium carbonate gives carbon dioxide and lime, which is of use in the glass, steel, and paper industries.

The carbonates tend to be soft, soluble in hydrochloric acid, and have a marked anisotropy in many physical properties (e.g., high birefringence) as a result of the planar structure of the carbonate ion.
What are the 4 uses of calcium carbonate?
Paper, Plastics, Paints, and Coatings: Calcium carbonate is the most widely used mineral in the paper, plastics, paints and coatings industries both as a filler – and due to its special white color - as a coating pigment.
What are the properties of calcium?
Uses and properties Calcium is a silvery-white, soft metal that tarnishes rapidly in air and reacts with water. Calcium metal is used as a reducing agent in preparing other metals such as thorium and uranium. It is also used as an alloying agent for aluminium, beryllium, copper, lead and magnesium alloys.
What are the 5 uses of calcium carbonate?
It has a role as an antacid, a food colouring, a food firming agent and a fertilizer. It is a calcium salt, a carbonate salt, a one-carbon compound and an inorganic calcium salt.
What is carbonate used for?
The main uses of carbonates is as raw materials in different industrial processes such as drug development, glass making, pulp and paper industry, sodium chemicals (silicates), soap and detergent production, paper industry, water softener, clay and concrete production, among others.
How does calcium carbonate work?
Calcium carbonate is an inorganic salt used as an antacid. It is a basic compound that acts by neutralizing hydrochloric acid in gastric secretions. Subsequent increases in pH may inhibit the action of pepsin. An increase in bicarbonate ions and prostaglandins may also confer cytoprotective effects.
What are the four properties of calcium?
A single atom of calcium contains 20 protons/electrons and 20 neutrons. Chemical properties of calcium, furthermore, include a cubic crystal structure, a white silvery color, and a density of 1.55 g/cm3 at 293 K. Calcium has four energy levels, with electrons count of 2, 8, 8, and 2 respectively.
What is the physical property of calcium?
Physical properties Calcium is a fairly soft metal with a shiny silver surface when first cut. The surface quickly becomes dull as calcium reacts with oxygen to form a coating of white or gray calcium oxide. Calcium's melting point is 850°C (1,560°F) and its boiling point is 1,440°C (2,620°F).

Does calcium carbonate absorb water?
Calcium carbonate reacts with water that is saturated with carbon dioxide to form the soluble calcium bicarbonate. This reaction is important in the erosion of carbonate rock, forming caverns, and leads to hard water in many regions.
What is the pH value of calcium carbonate?
At pH values of between about 6.5 and 10, bicarbonate is dominant. At pH values greater than about 10.5, the carbonate ion dominates.
What is calcium used for?
Your body needs calcium to build and maintain strong bones. Your heart, muscles and nerves also need calcium to function properly. Some studies suggest that calcium, along with vitamin D, may have benefits beyond bone health: perhaps protecting against cancer, diabetes and high blood pressure.

Occurrence
The main use of calcium carbonate is in the construction industry, either as a building material, or limestone aggregate for road building, as an ingredient of cement, or as the starting material for the preparation of builders' lime by burning in a kiln. However, because of weathering mainly caused by acid rain, calcium carbonate (in limestone form) is no longer used for building purposes on its o…
Geology
Calcium carbonate shares the typical properties of other carbonates. Notably it
• reacts with acids, releasing carbon dioxide (technically speaking, carbonic acid, but that disintegrates quickly to CO2 and H2O):
CaCO3(s) + 2 H (aq) → Ca (aq) + CO2(g) + H2O(l)
• releases carbon dioxide upon heating, called a thermal decomposition reaction, or calcination (to …
Calcination equilibrium
The vast majority of calcium carbonate used in industry is extracted by mining or quarrying. Pure calcium carbonate (such as for food or pharmaceutical use), can be produced from a pure quarried source (usually marble).
Alternatively, calcium carbonate is prepared from calcium oxide. Water is added to give calcium hydroxide then carbon dioxide is passed through this solution to precipitate the desired calcium c…
