Parchem is the leading supplier of Calcium Carbonate

May 01, 2013

Calcium Carbonate [CAS#: 471-34-1] is an inorganic chemical compound that is extracted from limestone, marble, and other mineral rock formations.  Parchem supplies calcium carbonate as a fine white powder or granulation for use in industrial and pharmaceutical applications.  Parchem offers different grades of calcium carbonate – technical grade calcium carbonate is used as a chemical building block, as a base, and as a source of both calcium and carbonate anion.  Parchem also supplies pharmaceutical grade calcium carbonate which is used in certain medical preparations such as nutritional calcium supplements and antacid tablets. 


Calcium Carbonate is often used as a chemical building block for the production of Calcium Oxide, also known as Quicklime.  Calcium oxide is produced by heating calcium carbonate to extreme temperatures over 800°C in a process called calcination.  Heating the calcium carbonate this way releases carbon dioxide from the molecule, leaving behind calcium oxide as a product of the reaction. 


Conversely, calcium carbonate is also prepared using calcium oxide as a starting material.  In this process, water is added to calcium oxide which drives a hydrolysis reaction that forms calcium hydroxide.  Once the calcium hydroxide solution is formed, carbon dioxide is passed through the solution in order to precipitate out calcium carbonate granules. 


Calcium Carbonate is used in several applications in the industrial, concrete, and oil markets.  Highly purified forms of calcium carbonate are also used in the food, beverage, and pharmaceutical markets. In the oil drilling industry, calcium carbonate is sometimes added to drilling muds and completion fluids to increase the density of the fluids.  In industrial, concrete, and building applications, calcium carbonate is used as a chemical building block for the preparation of building materials.  The purified calcium carbonate powder that Parchem supplies for pharmaceutical applications is used in the preparation of various medicines and tablets such as antacids.  It is also used as an acid neutralizing agent in certain food and beverage preparations that require a balanced pH level.


Parchem is the premier supplier of both industrial and pharmaceutical grade calcium carbonate.  For over 20 years, Parchem has been supplying high quality raw materials to the global food, pharmaceutical, nutritional, and specialty chemical markets.
