Surface Modification of Calcium Carbonate

How Does Surface Modification of Calcium Carbonate Improve Performance and Enable Precise Application Matching?

By

Calcium carbonate, as an inorganic powder material with abundant reserves, low cost, and environmental friendliness, has been widely used in plastics, rubber, coatings, papermaking, adhesives, and many other fields. However, it inherently exhibits hydrophilic and oleophobic surfaces, poor compatibility with organic matrices, and a strong tendency to agglomerate. These intrinsic drawbacks limit its application in […]

Calcium carbonate whisker modification

What Are Calcium Carbonate Whiskers?

By

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

How Many Types of Calcium Carbonate Are There? Understanding Their Unique Applications and Differences

By

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

Specific Surface Area Calcium Hydroxide Grinding Equipment

What Grinding Equipment Is Needed to Produce High–Specific Surface Area Calcium Hydroxide? And What Is It Used For?

By

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
