What is CaCO3 powder?
CaCO₃ (Calcium Carbonate) Powder is a natural minerals common, with a chemical formula Calcium carbonate, sourced from natural limestone or chemical synthesis. Nhờ Inertness, high purity, and reasonable price, CaCO₃ powder becomes key ingredients in many industries.
CaCO₃ can be extracted from nature in the form of limestone, or artificial production through the reaction between canxi oxit (CaO) và CO₂.

Properties of CaCO3 powder:
Physical Properties of Calcium Carbonate:
- Appearance: A white, powdery solid.
- Water solubility: Insoluble in water under normal conditions.
- Melting point: 825oC.
- Boiling point: There is no specific boiling point because it decomposes into CaO and CO2 before reaching its boiling point.
Chemical Properties of Calcium Carbonate:
- Solubility: Insoluble in water; it may dissolve when a large amount of CO2 is added to form calcium bicarbonate (Ca(HCO3)2).
- CaCO3 + CO2 + H2O → Ca(HCO3)2
- Reacts vigorously with acids: produces calcium salt and water, releasing CO2.
- CaCO3 + 2HCl → CaCl2 + CO2↑ + H2O
- Combustion reaction: When CaCO₃ is burned, it decomposes into calcium oxide (CaO) and CO₂ gas.
- CaCO3 → CaO + CO2
- Reaction with calcium hydroxide (Ca(OH)2): to produce water-soluble calcium bicarbonate.
- CaCO3 + Ca(OH)2 → 2Ca(HCO3)2

Calcium carbonate (CaCO₃) typically occurs naturally and is formed through natural processes such as precipitation in seawater, crystallization in caves, or from the fossils of marine organisms. However, CaCO₃ can also be synthesized chemically through reactions that can be carried out in a Laboratory. A common method involves using carbonic acid and calcium salts. The following is the chemical equation for the synthesis of CaCO₃:
- Use of Calcium Chloride (CaCl₂) and Sodium Carbonate (Na₂CO₃):
- CaCl2 + Na2Carbon Monoxide3 → CaCO3 + 2NaCl
- In this reaction, calcium chloride (CaCl₂) and sodium carbonate (Na₂CO₃) react to form calcium carbonate (CaCO₃) and sodium chloride (NaCl), a salt.
- Use of Calcium Oxide (CaO) and Carbon Dioxide (CO₂):
- CaO + CO2 → CaCO3
In this reaction, calcium oxide (CaO), also known as quicklime, reacts with carbon dioxide (CO₂) to form calcium carbonate (CaCO₃).
Applications of CaCO₃ powder in daily life and manufacturing:
- Construction Industry – Key Components of Cement and Concrete
- Calcium carbonate (CaCO₃) powder is the primary raw material for the production of cement, concrete, and ceramic tiles. When heated, CaCO₃ decomposes into calcium oxide (CaO) and CO₂, forming a key component in the cement manufacturing process.
- Increasing the Strength of Concrete
- Used as an additive to help reduce production costs
- Add a glossy finish to ceramic tiles
- Paint Industry – Whitening Agents & Durability Enhancers
- In the paint manufacturing industry, ultrafine CaCO₃ powder is used as a filler, which helps:
- Enhance brightness
- Improve coverage & adhesion
- Reducing paint production costs
- Plastics Industry – Improving Durability, Reducing Costs
- CaCO₃ is an important additive in plastics manufacturing, helping to:
- Increase hardness and mechanical strength
- Improve fire resistance
- Reducing the cost of plastic raw materials
- Animal Feed Industry – Mineral Supplements
- Calcium Supplementation for Livestock and Poultry
- Helps support bone and tooth development
- Stabilizes the digestive system and improves animal health
- Water Treatment – pH Adjustment, Water Softening
- CaCO₃ helps regulate pH, remove heavy metal ions, and make the water cleaner.
- Reducing Water Hardness
- Improving the Quality of Drinking Water and Industrial Water

Extended FAQ – In-Depth Answers About CaCO₃ Limestone Powder
- Is CaCO₃ powder harmful to human health?
- CaCO₃ limestone powder is a natural mineral and non-toxic if used correctly. However, if Continuous inhalation of stone dust in an unprotected environment, may irritate the respiratory system or affect the lungs with prolonged exposure. During production, workers should wear masks and safety goggles to avoid inhaling CaCO₃ dust. For food, Food-grade CaCO₃ is safe for use in confectionery, pharmaceuticals, and calcium supplements.
- Can CaCO₃ powder completely replace other additives in manufacturing?
- CaCO₃ Powder cannot be completely replaced all additives used in production, but it may significantly reduce costs when used as a filler in paint, plastics, paper, and animal feed. Depending on purity and particle size, CaCO₃ can be used to increase hardness, improve coverage, or enhance a product’s heat resistance. However, in many industries, Other additives are still necessary to ensure the product's mechanical and physical properties and quality.
- Is CaCO₃ powder soluble in water, and why is it still used in water treatment?
- CaCO₃ Powder insoluble in water Under normal conditions, but is water-soluble High CO₂ content, tạo ra canxi bicarbonate (Ca(HCO₃)₂), a soluble form of calcium. In water treatment, CaCO₃ is used to adjust the pH It neutralizes acidic water, helping to stabilize the filtration system and protect pipes from corrosion. In addition, CaCO₃ helps reduce water hardness by precipitating heavy metal ions, making the water cleaner.
- Why do prices for CaCO₃ powder vary among suppliers?
- The price of CaCO₃ powder depends on purity, particle size, source of extraction, and production process. Limestone powder has High CaCO₃ content (on 98%) and ultra-fine particle sizes are typically more expensive because a more complex grinding and processing procedure. In addition, shipping costs, the supplier’s brand, and quality standards (such as ISO 9001, HACCP) also affects prices. When buying rock powder, you should A comparison of price and quality, rather than simply choosing the cheapest product and ignoring important factors such as whiteness and purity.
- What is the difference between natural CaCO₃ powder and synthetic CaCO₃ powder?
- Natural CaCO₃ limestone powder is mined from limestone, marble, or seashells and ground into a fine powder. This type has High CaCO₃ content, common in various industries construction, plastics, paint, paper. Meanwhile, synthetic CaCO₃ powder is produced through a reaction between calcium oxide (CaO) and CO₂, cho ra products with higher purity but production costs are also higher. Synthetic CaCO₃ is commonly used in healthcare, pharmaceuticals, and food to ensure higher safety standards.
