Product Description
Calcium carbonate, an inorganic compound denoted by the chemical formula CaCO3, ranks among the most prevalent substances on Earth. It is present in rocks like limestone and marble and constitutes the main component of the hard structures in numerous organisms, such as shells and coral skeletons.
Regarding its physical traits, calcium carbonate presents as a white, tasteless, and odorless solid. It comes in diverse crystalline forms, with calcite and aragonite being particularly common. Calcite crystallizes in the trigonal crystal system and typically takes on a rhombohedral shape. Aragonite, on the other hand, belongs to the orthorhombic crystal system, and its crystals often appear columnar or acicular. The density of calcium carbonate fluctuates slightly depending on factors related to its crystal form, generally ranging around 2.7 - 2.9 g/cm³. It has a medium level of hardness, registering approximately 3 on the Mohs scale.

Application
Industrial - grade calcium carbonate plays a crucial role as a paper filler in the paper - making industry. It has the ability to enhance the whiteness, opacity, and smoothness of paper. In the course of paper - making, calcium carbonate is incorporated among the paper fibers. This placement effectively blocks the passage of light, thereby enhancing the opacity of the paper.
Calcium carbonate is extensively employed as a filler within the building materials sector. During the manufacturing of cement, the addition of a proper quantity of industrial - grade calcium carbonate can enhance the cement's performance. It is capable of augmenting the strength and hardness of the cement while simultaneously cutting down on production costs. Take, for instance, the mortar utilized in ordinary buildings. Incorporating calcium carbonate into this mortar can make it more compact and firm, and it also contributes to a reduction in the amount of cement required.
Industrial - grade calcium carbonate serves as a frequently - used filling material in the plastics industry. When added to plastic products, it has the effect of increasing the volume of the plastic, which in turn helps to lower the production cost. For example, during the production of polyvinyl chloride (PVC) plastic pipes, the incorporation of calcium carbonate can raise the density of the pipes. This increase in density further enhances the rigidity and hardness of the pipes, allowing them to endure pressure more effectively.
