Excellent Dispersion Properties
Our Calcium Carbonate stands out from its counterparts due to its purity, whiteness, high wettability, and weather resistance.
Calcite Calcium Carbonate (CaCO₃) makes up more than 4% of the Earth’s crust and is found throughout the world. Its most common natural forms are chalk, limestone, and marble—formed by the sedimentation of shells from small fossilized snails, shellfish, and coral over millions of years. Although all three forms are chemically identical, they differ in several aspects, including purity, whiteness, texture, and homogeneity.
Many of us first encounter calcium carbonate in the school classroom, where we use blackboard chalk. Chalk has served as a writing tool for over 10,000 years and is a fine, microcrystalline material. As limestone, calcium carbonate is a biogenic rock and more compact than chalk. In its marble form, calcium carbonate is a coarse-crystalline, metamorphic rock formed when chalk or limestone undergoes recrystallization under high temperature and pressure.
For industrial purposes, calcium carbonate is extracted through mining or quarrying. It can be obtained in its pure form from marble or produced synthetically by passing carbon dioxide through a solution of calcium hydroxide. This process yields a product known as precipitated calcium carbonate (PCC), which has a very fine and controlled particle size, typically around 2 microns in diameter.
