Porcelain-White Composite Calcium Carbonate

Why Do Customers Prefer Porcelain-White Composite Calcium Carbonate?

By

In industries such as plastics, coatings, rubber, papermaking, and artificial marble, calcium carbonate is one of the most widely used and cost-effective functional fillers. In recent years, however, a more advanced and high-performance material—porcelain-white composite calcium carbonate—has been rapidly gaining popularity among customers. So what makes it stand out among so many filler materials? This […]

What You Need to Know About Calcium Carbonate Modification?

By

Calcium carbonate (CaCO₃) is a widely available mineral used across many industries. Structurally, it exists in three main crystal forms: calcite, aragonite, and vaterite. Each form differs in morphology and stability, with calcite being the most stable and commonly used in industrial applications. Although unmodified calcium carbonate is widely utilized, it has several limitations. Due

Toothpaste Abrasive

How Does the Particle Size of Natural Calcium Carbonate Abrasives Affect the Core Performance of Fluoride Toothpaste?

By

Natural calcium carbonate (NCC) is a commonly used abrasive in toothpaste. Typical commercial grades include 325 mesh (D97 ≈ 45 μm) and 400 mesh (D97 ≈ 38 μm). In recent years, toothpaste formulation technology has advanced rapidly. Ultrafine grinding processes have also made significant progress. As a result, finer natural calcium carbonate abrasives are becoming

How Does a Pin Mill Effectively Disperse Nano-Calcium Carbonate?

By

Nano-calcium carbonate (nano-CaCO₃) is an ultrafine functional filler with a primary particle size typically below 100 nm. It is widely used in plastics, rubber, coatings, inks, and adhesives to improve mechanical strength, opacity, and rheological properties. However, due to its high surface energy and strong van der Waals forces, nano-calcium carbonate tends to agglomerate during

The Six Perspectives: What Do We Need to Know About Ground Calcium Carbonate?

By

1. What Is Ground Calcium Carbonate? Ground calcium carbonate (GCC) is a white powder produced by mechanically grinding natural calcium carbonate minerals such as calcite, limestone, dolomite, chalk, and shells. It typically appears as a gray-white or light brown granular solid with slight acidity, high purity, and stable composition. As a widely used industrial raw
