Calcium carbonate heavy powder is a chemical compound with the chemical formula CaCO3. It is a white, odorless powder that occurs naturally in various minerals, such as limestone, marble, and chalk. Calcium carbonate is commonly used in a wide range of industries due to its versatile properties. Here's an introduction to this product:

TEST REPORT OF CALCIUM CARBONATE

1. 1:Chemical Composition:Calcium carbonate heavy powder consists of three elements: calcium (Ca), carbon (C), and oxygen (O). Its molecular weight is approximately 100.09 g/mol.

2. 2:Physical Properties:

   • Appearance:Fine, white powder.
   • Density:Calcium carbonate heavy powder has a high density, typically ranging from 2.7 to 2.9 g/cm³.
   • Melting Point:It decomposes at high temperatures, not melting as a pure substance.

3. 3:Applications:

   • Construction:Calcium carbonate is commonly used as a filler in the production of construction materials like paints, adhesives, and sealants. It improves the strength and durability of these materials.
   • Pharmaceuticals:It is used as an active ingredient in antacids and calcium supplements.
   • Agriculture:Calcium carbonate is utilized as a soil conditioner to neutralize acidic soils and provide essential calcium to plants.
   • Paper Industry:It is used as a filler and coating pigment in the papermaking process to improve paper quality.
   • Plastics and Rubber:Calcium carbonate enhances the stiffness and impact resistance of plastics and rubber products.
   • Food Industry:It is used as a food additive (E170) for various purposes, including as a calcium supplement, anti-caking agent, and acidity regulator.

4. 4:Heavy vs. Light Calcium Carbonate:Calcium carbonate can be classified as "heavy" or "light" based on its particle size and density. Heavy calcium carbonate has larger particles and a higher density, making it suitable for applications where increased bulk density or greater opacity is required.

5. 5:Handling Precautions:Calcium carbonate is generally considered safe, but as with any fine powder, precautions should be taken to avoid inhalation. It should be handled in a well-ventilated area, and personal protective equipment, such as dust masks and goggles, may be necessary.

6. 6:Packing and Storage:Calcium carbonate heavy powder is typically available in bags or containers. It should be stored in a dry place away from moisture to prevent clumping.

7. 7:Regulatory Compliance:In many regions, calcium carbonate heavy powder used in food, pharmaceuticals, and other applications must meet specific quality and safety standards. Ensure that the product you use complies with relevant regulations in your area.

8. 8:Supplier Information:When purchasing calcium carbonate heavy powder, it is essential to source it from reputable suppliers to ensure product quality and consistency.
