Precipitated calcium carbonate (PCC)
Our Precipitated Calcium Carbonate (PCC) is a brilliant white, ultra-fine crystalline powder, meticulously engineered for a consistent particle size distribution and exceptional dispersibility. This ensures superior performance and seamless integration into your applications.
The Imperial Minerals Process:
The journey to our high-quality $\text{PCC}$ begins with high-purity limestone, expertly calcined in our advanced kilns to yield quicklime. This quicklime undergoes controlled slaking and subsequent carbonation, forming a pristine PCC slurry. Through precise filtration and drying, we transform this slurry into the pure, fine white PCC powder you rely on.
