Ground calcium carbonate (GCC) powder, derived from natural marble, is crucial in many industries, including construction, coatings, plastics, and rubber. The physical and chemical properties of GCC depend on the crystal structure and particle size of the raw marble. This article explores the characteristics and performance of different marble types used for ground calcium carbonate

Iceland spar（ chemical composition is CaCO3）,a colorless and transparent pure calcite crystal, is a unique natural mineral with exceptional optical properties. It has the highest birefringence and the strongest polarization performance among transparent minerals. This makes it irreplaceable as a natural crystal, which cannot be artificially synthesized. Iceland spar is an excellent optical and optoelectronic

Calcium carbonate is widely used in filling polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), acrylonitrile butadiene-styrene copolymer (ABS) and other resins. Adding calcium carbonate has a certain effect on improving certain properties of plastic products to expand their application range. In plastic processing, adding calcium carbonate to masterbatch can reduce resin shrinkage, improve rheology, control

Dry grinding of calcium carbonate powder is a common process for producing ground calcium carbonate (GCC). Although it is widely used due to its low equipment investment, mature technology, simple process, low energy consumption and high single machine output. However, some problems will be encountered in the actual production process, including but not limited to:

Although both calcite powder and marble powder belong to calcium carbonate powder, they have obvious differences in specific applications due to different raw material sources, structural characteristics and processing technologies. Understanding their differences will help make more reasonable material choices in industries such as plastics, coatings, and building materials. Thereby improving product performance and cost-effectiveness.

Heavy calcium carbonate powder is a typical low-carbon, environmentally friendly inorganic non-metallic mineral material. It is one of the important fillers for breathable membranes. In the preparation of breathable membranes, heavy calcium powder acts as a “porogen.” Through unidirectional or biaxial stretching, polyester matrix and heavy calcium particles separate. Micro-channels are formed between the filler

When formulating plastic masterbatches, understanding the difference between talcum and calcium carbonate is crucial for performance and economics. While calcium carbonate (specifically from calcite crystal ore) is the predominant filler used in most masterbatches, talcum powder is also a viable option. A key ​​difference between talcum and calcium carbonate​​ lies in ​​cost​​, with calcium carbonate

Surface modification is crucial for enhancing calcium carbonate‘s performance, applicability, and market expansion. In the future, functionalization and specialization will be the main trends in calcium carbonate development. The demand for surface modified calcium carbonate will continue to grow. It’s essential to base surface modification on its mechanism. Consider the substrate, formulation, and technical requirements
