Among the family of inorganic powder materials, calcium carbonate (CaCO₃) is undoubtedly a shining star. Composed of calcium, carbon, and oxygen, it is widely found in nature in the form of limestone, marble, and calcite. At the same time, it can also be produced on a large scale through industrial synthesis. Thanks to its abundant

Calcium carbonate has become one of the most widely used inorganic fillers in plastic film production. This is mainly due to its low cost, high whiteness, and balanced overall properties. When processed into filler masterbatch for film production, calcium carbonate helps simplify manufacturing processes. It also improves compounding efficiency and increases productivity. In addition, dust

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

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
