Precipitated calcium carbonate

Understanding Precipitated Calcium Carbonate

Precipitated Calcium Carbonate (PCC) is a versatile and essential chemical compound derived from lime, widely used in various industries. It is a fine white powder that is created through a specialized chemical process in which carbon dioxide reacts with slaked lime, resulting in the formation of calcium carbonate with a precipitated structure. The unique properties of PCC make it a popular choice for applications ranging from industries to consumer products.

Types of Precipitated Calcium Carbonate

Precipitated Calcium Carbonate comes in several different grades and types, catering to distinct applications and performance requirements. The principal types include:

• Coated PCC: Enhances dispersion and provides improved performance in applications like plastics and paints.
• Uncoated PCC: Offers high purity and stability, ideal for pharmaceuticals and food applications.
• Specialty PCC: Tailored for specific uses, such as rubber or paper production, with unique properties that enhance the product's performance.
• Micronized PCC: A finer grade that provides high surface area, suitable for demanding applications like tinting in the automotive industry.
