Product Description Detailed PhotosCalcium carbonate is an inorganic compound with the chemical formula CaCO3. It is one of the most common substances on the earth. It exists in rocks such as limestone and marble and is also the main component of the hard tissues of many organisms, such as shells and coral skeletons.In terms of physical properties, calcium carbonate is a white solid, tasteless and odorless. It has a variety of crystalline forms, among which calcite and aragonite are more common. Calcite belongs to the trigonal crystal system and is usually in the shape of a rhombohedron; aragonite belongs to the orthorhombic crystal system and its crystals are mostly columnar or acicular. Its density varies slightly due to factors such as crystalline form and is generally around 2.7 - 2.9 g/cm3. It has a moderate hardness with a Mohs hardness of about 3.Product ParametersProduet Name:Calcium carbonateMolecular Formula:CaCO3Appearance: White powderProduct Calcium carbonate(heavy)25kg/bagItems of test standardTest resultsSensory indexWhite or gray-white powdercoincidenceIdentification testPass the testpassAssay %98-100100Insolubles in HCl%≤0.200.06Dissociate alkaliPass the test passMagnesium and alkali metal %≤1.00.79Loss on drying %≤2.00.23Barium (mg/kg)≤300<300Cd (mg/kg)≤2.0<2.0F (mg/kg)≤50<50As (mg/kg)≤3.0<3.0Lead (mg/kg)≤3.0<3.0Hg (mg/kg)≤0.5<0.5Iron ≤0.1%<0.1%Heavy metals (mg/kg)≤20<20ApplicationNatural limestone is composed of calcium carbonate, which can be obtained by mining and processing limestone. Lightweight calcium carbonate can be used as a leavening agent, flour processing agent, anti caking agent, acidity regulator, nutritional enhancer, solidifying agent, etc. It is a filling material for rubber, which can make the rubber have a bright color, high elongation, high tensile strength, and good wear resistance. It is also used as a filler in industries such as artificial leather, wires, polyvinyl chloride, coatings, inks, and papermaking.Definition & OriginIndustrial-grade calcium carbonate (CaCO3) is a mechanically processed powder obtained from high-calcium limestone, marble, or chalk. It is classified as Ground Calcium Carbonate (GCC) or Precipitated Calcium Carbonate (PCC) depending on the manufacturing route. GCC is produced by dry or wet grinding of natural ores; PCC is chemically precipitated for higher purity and finer particle size .Packaging & Shipping25kg/ 1000kg Bag Strictly Deliver the goods in accodance with the contract.Storage: Environment? Store in a cool, dry, well-ventilated warehouse.? Maintain ambient temperature below 35 °C; avoid sudden temperature fluctuations.? Keep relative humidity < 60 % to prevent moisture absorption and caking.Physical Handling? Stack on pallets or raised platforms at least 20 cm above the floor and 1 m away from walls.? Maximum pallet height: 1.5 m for 25 kg / 50 kg bags; 2 layers for 1 000 kg big bags.? Use first-in-first-out (FIFO) rotation to limit storage time to 24 months from production date.Protection? Keep containers tightly closed when not in use.? Protect from direct sunlight, rain, and sources of mechanical shock.? Segregate from acids, oxidizing agents, and materials that generate CO2 or heat on contact.Inspection? Inspect bags regularly for tears or moisture ingress; repackage damaged bags immediately.
