Calcium carbonate, as a high-quality, low-cost, and environmentally friendly inorganic filler, has become one of the most widely used fillers in the papermaking industry due to its high whiteness, good dispersibility, strong chemical stability, and abundant resources. It is extensively applied in the production of cultural paper, packaging paper, and tissue paper. In papermaking, calcium […]
You already know that achieving high-quality ground calcium carbonate ultrafine grinding is a constant battle between particle fineness and energy consumption. But how do you consistently hit precise D97 targets without destroying your profit margins? In this guide, I’m going to break down the exact processing line—specifically the Ball Mill and Air Classifier system—that is
Whiskers are single-crystal materials that grow in a filament-like or needle-like shape. They resemble short fibers, but their dimensions are much smaller. Whisker materials can be classified into organic whiskers and inorganic whiskers. Common inorganic whisker materials include SiC, Si₃N₄, K₂Ti₁₃O₃₀, Al₁₈B₄O₃₃, ZnO, MgO, Al₂O₃, and CaCO₃. The atomic structure inside a whisker is highly

Calcium carbonate (CaCO₃) is a common inorganic compound, commonly known as limestone, marble, or chalk. It is neutral in nature, has low solubility in water, but readily dissolves in hydrochloric acid. Thanks to its abundant sources and low cost, calcium carbonate is widely used across many industries. It also offers good chemical stability, making it
Nano calcium carbonate refers to a functional inorganic filler with a particle size of 1–100 nm. It is widely used in rubber, plastics, papermaking, inks, coatings, sealants and adhesives, pharmaceuticals, toothpaste, food, and other fields. However, different applications have distinct requirements for particle size distribution, crystal form, oil absorption value, dispersion, and other properties. Application
In industries such as plastics, rubber, coatings, papermaking, cables, and construction materials, calcium carbonate is one of the most widely used inorganic fillers. It plays a critical role in product performance and cost control. However, in practical applications, Precipitated Calcium Carbonate (PCC) and Ground Calcium Carbonate (GCC) are often confused or improperly selected. This can
Calcium carbonate, as an inorganic mineral with abundant natural reserves and excellent cost performance, has become one of the most widely used inorganic fillers in the plastics industry. This is due to its low cost, high whiteness, good chemical stability, and strong mechanical compatibility with polymer materials. It can effectively reduce production costs while improving
When calcium hydroxide is mentioned, most people still think of traditional applications such as construction plastering or soil pH adjustment. However, today’s protagonist—high–specific surface area calcium hydroxide—has long moved beyond these conventional roles. Thanks to its exceptionally high specific surface area (30–80 m²/g or even higher), it is reshaping application boundaries and driving a quiet
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
Why is Calcium Carbonate the “Star” of Inorganic Powders ? Read More »
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
