Calcium carbonate, with the CAS number 471 - 34 - 1, is a widely used inorganic compound. It exists in nature in several mineral forms, including calcite, aragonite, and vaterite. Our factory - supplied calcium carbonate is of high quality and comes at a low price.
Chemical Formula: CaCO₃
Molecular Weight: 100.0869 g/mol
Appearance: It is a white, odorless powder.
Solubility: Insoluble in water and alcohol, but soluble in acids with effervescence.
Calcium carbonate has a wide range of applications in various industries:
In the paper industry, it is used as a filler and coating pigment. As a filler, it improves paper opacity, brightness, and printability. When used as a coating pigment, it enhances the smoothness and gloss of the paper surface.
It is added to plastics to improve mechanical properties such as stiffness, hardness, and dimensional stability. It also reduces the cost of plastic products by replacing more expensive polymer materials.
Calcium carbonate is used as an extender pigment in paints and coatings. It improves the hiding power, durability, and weather resistance of the coatings, while also reducing the cost.
It is used as a calcium supplement in pharmaceuticals. Calcium is essential for maintaining strong bones and teeth, and calcium carbonate provides a convenient and inexpensive source of calcium.
In industrial processes such as paper making, plastics production, and paint manufacturing, calcium carbonate is usually added in powder form. The dosage depends on the specific requirements of the product and the process. For example, in paper filling, the addition rate can range from 10% to 30% by weight of the pulp.
When used as a dietary supplement, it should be taken with food to enhance absorption. The recommended daily intake of calcium for adults is around 1000 - 1200 mg, and the dosage of calcium carbonate should be adjusted accordingly. It is advisable to consult a healthcare professional before starting any calcium supplement regimen.
A paper mill was facing issues with paper quality, including low opacity and poor printability. They decided to use our calcium carbonate as a filler. By adding 20% calcium carbonate to the pulp, they observed a significant improvement in paper opacity, which increased from 80% to 85%. The printability also improved, with sharper and clearer images. The cost of production decreased due to the lower price of calcium carbonate compared to other fillers, and the overall quality of the paper products was enhanced.
A plastic manufacturer wanted to improve the stiffness of their plastic products while reducing costs. They incorporated 15% calcium carbonate into their plastic formulation. The resulting plastic products showed a 20% increase in stiffness, and the cost per unit decreased by 10%. The calcium carbonate also improved the surface finish of the plastic products, making them more appealing to customers.
