About Calcium Carbonate

Calcium carbonate, also known as marble, is a metamorphic rock composed of coarse crystalline grains formed when chalk or limestone recrystallizes under high temperature and pressure. You can create calcium carbonate by adding carbon dioxide to calcium hydroxide solutions, or you can create it from marble.

Calcium Carbonate Properties:

  • CAS No.: 471-34-1
  • Formula: CaCO3
  • Molecular Weight: 100.09
  • EINECS: 207-439-9
  • Density: 2.93 g/ml at 25 °C(lit.)
  • Melting Point: 825 °C
  • Solubility: Insoluble in water
  • Appearance: White powder

How does it work:

The inorganic salt calcium carbonate is used as an antacid. In gastric secretions, it neutralizes hydrochloric acid by acting as a basic compound. As pH increases, pepsin may be inhibited. Increasing bicarbonate ions and prostaglandins may have cytoprotective effects as well.

Applications Or where it is used:

The calcium carbonate supplement is used when your diet does not contain enough calcium. The body needs calcium for healthy bones, nervous system, muscles, and heart. As an antacid, calcium carbonate helps with heartburn, acid indigestion, and upset stomach.

Manufacturing process:

Calcium carbonate has three crystalline polymorphs: calcite, aragonite, and vaterite. In the carbonation process, these crystals can be produced by changing various conditions such as concentration and temperature of lime milk, introduction rate of CO2 gas, and whether or not chemicals are added.

How to use:

You should take calcium carbonate exactly as directed. Make sure you do not take it in excess, less, or more often than prescribed by your doctor. Take this medicine with food or after eating when used as a dietary supplement. Chewable tablets should be chewed thoroughly before swallowing them. Do not swallow whole chewable tablets.

Side effects:

  • Loss of appetite
  • Vomiting
  • High calcium levels
  • Low phosphate levels
  • Constipation
  • Gas 
  • Nausea
  • Milk-alkali syndrome

Warnings and precautions while using this product:

During pregnancy, calcium carbonate should be used with caution if the benefit outweighs the risk. Studies of animals show risk, but human studies have not been conducted. 


Versatility and High Purity

With a purity level of 98% and pharmaceutical-grade classification, this Calcium Carbonate suits a wide array of applications, including medicinal formulations, food industry uses, and numerous industrial purposes. Its fine particle size (up to 5 microns) ensures consistent performance and easy integration in diverse processes.


Safe and Stable Formulation

Non-poisonous and devoid of odor or taste, this white powder guarantees safety in usage. It is packaged securely in HDPE bags with liners to prevent moisture ingress, and its low moisture content, along with proper storage, supports a shelf life of 1 to 3 years.


Reactive and Reliable Performance

Calcium Carbonate reacts with acids to release CO2, a property utilized in various chemical and industrial processes. Its insolubility in water makes it ideal for formulations where long-term structural integrity or controlled reactivity is required.

FAQ's of Calcium Carbonate:


Q: How should Calcium Carbonate be stored to maximize its shelf life?

A: Store Calcium Carbonate in a cool, dry location, away from moisture and direct sunlight, in its original HDPE bag with liner. Proper storage ensures product integrity and extends shelf life to between 1 and 3 years.

Q: What are the main uses of this Calcium Carbonate?

A: This product is widely used in pharmaceuticals as an active ingredient or excipient, as a food additive for fortification or anti-caking, and in industrial applications such as fillers, coatings, and as a neutralizing agent.

Q: What benefits does this high-purity, pharmaceutical-grade Calcium Carbonate offer?

A: Its 98% purity and fine particle size ensure uniform blending in formulations, minimal impurity introduction, and compliance with rigorous industry standards, making it suitable even for sensitive pharmaceutical and food applications.

Q: How is Calcium Carbonate typically processed for commercial use?

A: This product is produced through precipitation (yielding PCC) or by refining naturally sourced minerals (GCC). Both methods result in a highly pure, fine white powder suitable for demanding industrial and pharmaceutical markets.

Q: When does Calcium Carbonate react, and what is released during this process?

A: Calcium Carbonate reacts with acids, commonly in situ within certain formulations or industrial reactions, releasing carbon dioxide (CO2) during the reaction.

Q: Where does the supplied Calcium Carbonate originate, and who supplies it?

A: Manufactured, distributed, and supplied in India, this product is available from various exporters, suppliers, and traders, ensuring reliable access for both domestic and international customers.

Q: What process ensures the low moisture content and fine particle size of this product?

A: Advanced precipitation or purification processes, along with controlled milling and handling, deliver a powder with less than 0.2% moisture and particles up to 5 microns, supporting superior dispersion and application performance.
