💡 Commercial Applications
Calcium carbonate, a naturally occurring substance used in a wide range of commercial and industrial applications, is commonly utilized as a filler material in the production of paper, plastics, paints, and coatings. Its high brightness and whiteness make it a popular choice for enhancing the opacity, gloss, and smoothness of various products.
In addition to its commercial and industrial applications, calcium carbonate plays a crucial role in the pharmaceutical industry, where it is used as an active ingredient in antacids to treat conditions such as heartburn, indigestion, and acid reflux. Its ability to neutralize excess stomach acid makes it an effective and widely prescribed medication for alleviating the symptoms of gastrointestinal disorders.
Moreover, calcium carbonate is utilized in the production of dietary supplements and vitamins due to its high calcium content, essential for maintaining strong and healthy bones and teeth. Its bioavailability and easy absorption by the body make it a valuable ingredient in various health products aimed at improving bone density and preventing osteoporosis.
⚗️ Chemical & Physical Properties
Calcium Carbonate is a white, odorless solid that is commonly found in nature as limestone, marble, and chalk. It has a powdery texture and does not have a distinct smell.
The molar mass of Calcium Carbonate is approximately 100.09 g/mol and its density is around 2.71 g/cm³. In comparison to common household items, Calcium Carbonate has a higher molar mass than table salt (NaCl) and a lower density than aluminum foil.
Calcium Carbonate has a melting point of 825 °C and a boiling point of 1,480 °C. In comparison to common household items, Calcium Carbonate has a higher melting point than sugar and a lower boiling point than water.
Calcium Carbonate is sparingly soluble in water, with a solubility of approximately 0.013 g/100 mL at 25 °C. It has a low viscosity, making it easy to mix and dissolve in water. In comparison to common household items, Calcium Carbonate is less soluble in water than table salt and has a lower viscosity than honey.
🏭 Production & Procurement
Calcium Carbonate is primarily produced through a chemical process known as the Solvay process. This involves the reaction of sodium carbonate with calcium chloride to produce calcium carbonate, sodium chloride, and carbon dioxide as byproducts. The resulting calcium carbonate can then be further processed and purified for various industrial applications.
Once Calcium Carbonate has been produced, it can be procured from specialized chemical suppliers or industrial manufacturers. It is typically available in various grades and forms, such as powder or granules, to suit different applications. The procurement of Calcium Carbonate may involve bulk orders for industrial use or smaller quantities for laboratory research purposes.
Transporting Calcium Carbonate may involve the use of specialized containers or packaging to ensure its safe and secure delivery. Depending on the volume and distance of transportation, Calcium Carbonate may be delivered by truck, rail, or sea freight. Proper handling and storage of Calcium Carbonate is essential to prevent contamination or degradation during transit.
⚠️ Safety Considerations
