What is Calcium Carbonate?
Calcium Carbonate (CaCO₃) is a natural quartz that is commonly found as limestone, marble, and chalk. It's a white powder, insoluble in water, nontoxic, and friendly with nature.
Chemical formula: CaCO₃ – Melting point: ~825°C – Hardness: Mohs 3 – Specific gravity: 2.71 g/cm³
In a world of high-precision and high-performance manufacturing, raw material is a key to success. Calcium carbonate, or limestone powder, is a material that helps to enhance the material content, reduce the cost, and enhance the quality of manufacturing, such as rubber, plastic, paint, and paper, including oil drilling.
Calcium Carbonate types
Ground Calcium Carbonate (GCC)
Which is from natural stone crushing, such as limestone, marble, or chalk. It has a hardness particle size up to the smoothness particle size, using the filter for rubber, plastic, and paints to increase the material content and reduce the cost. Perfect for the industry that requires mechanical strength.
Precipitated Calcium Carbonate (PCC)
Manufacturing from chemical precipitation processes that are higher in whiteness and fineness than GCC. It's a particle-shaped controllable (e.g., needles, spheres, scales) commonly used in the paper, plastics, paint, and pharmaceutical industries that require a high degree of whiteness and quality.

Key features of calcium carbonate
Pure white powder, well distributed, and helps to smooth products texture
The chemical's stability and durability to pH acid-base, including high heat
Nontoxic and safe. It's a certified guarantee from the FDA/EFSA
Quicklime is used as a Filler to increase the material content and reduce the cost
Quicklime is used as a LCM (Lost Circulation Material) in the oil drilling and gas industries
Industrial Applications:
Rubber and plastic → Decrease the material content and improve strength, and smoothness, such as PVC and white rubber
Color and coating → Enhancing the lightness, opacity, and durability of color texture
Paper → Used as a filler and coating, enhancing the whiteness, smoothness, and quality of the printer
Oil drilling and gas → Used for pressure control and to seal the leak (LCM Grade)
Food and pharmaceutical → Used as a filler of E170, building the calcium, antacids and stabilizers
The advantage of calcium carbonate in real-life uses
Food → Used as a calcium supplement (Food Additive E170) to nourish bones and teeth
Pharmacy → Used as an antacid, relieves acid reflux and indigestion
General stuff → Commonly used in paper, paint, plastic, rubber, and the cosmetic industry
Calcium carbonate is not only used in the rubber, plastic, paint, paper, food, and pharmacy industries. But it also has a big role in people's lives. From food to the general, and it's a material that's enhancing the quality, reducing the cost, and increasing safety.
