Product Description Product DescriptionCalcium carbonate is an inorganic compound. The following is a detailed introduction to it:Basic InformationChemical formula: CaCO3English name: Calcium CarbonateMolecular weight: 100.09Physical and Chemical PropertiesAppearance: It is a white solid, usually in the form of powder or lump.Density: Approximately 2.7 - 2.95g/cm^3Melting point: 825°C (Under standard atmospheric pressure, it decomposes into calcium oxide and carbon dioxide when the temperature exceeds this value.)Solubility: It is insoluble in water, with a very low solubility in water. However, it can dissolve in dilute acids such as hydrochloric acid and nitric acid, generating carbon dioxide gas at the same time. Forms of ExistenceCalcium carbonate is widely present in nature and is the main component of many rocks, such as limestone, marble, calcite, etc.It is also the main component of the skeletons or shells of some organisms, such as seashells and coral reefs.Main ApplicationsConstruction IndustryIt is one of the important raw materials for cement production. During the cement production process, calcium carbonate undergoes a series of processes such as high - temperature calcination and reacts with other raw materials to form the main components of cement.It is used in construction stone materials. Marble, etc. can be directly used for building decoration, such as the laying of walls and floors.Plastics IndustryAs a filler added to plastics, it can improve the hardness, heat resistance, dimensional stability and other properties of plastics, and at the same time reduce costs.Rubber IndustryIt is an important filler and reinforcing agent for rubber products. It can improve the processing performance of rubber and enhance the wear resistance, tear resistance, etc. of rubber products.Paper - making IndustryIt is used as a filler and coating pigment for paper, which can improve the whiteness, opacity, smoothness and printability of paper.Pharmaceutical IndustryIt can be used as a calcium supplement for the prevention and treatment of calcium deficiency diseases, such as osteoporosis, tetany, rickets, etc.It can also be used as a pharmaceutical intermediate in some drug synthesis reactions.Food IndustryAs a food additive, it can be used as a leavening agent, flour treatment agent, anti - caking agent, etc. For example, in bread, biscuits and other foods, it can make the food porous and have a better taste.Production MethodsNatural Ore Processing Method: Using natural ores such as limestone as raw materials, through processes such as mining, crushing and grinding, calcium carbonate products with different fineness can be obtained, such as heavy calcium carbonate.Chemical Synthesis Method: Usually, limestone is used as the raw material. First, the limestone is calcined at high temperature to generate calcium oxide. Then, calcium oxide reacts with water to form calcium hydroxide. Subsequently, calcium hydroxide reacts with carbon dioxide to form calcium carbonate precipitate. After processes such as filtration and drying, the product is obtained, such as light calcium carbonate.Detailed Photos Product ParametersProduct name:Calcium carbonateAppearance:White powderCAS No.: 471-34-1EINECS No.:207-439-9Molecular formula:CCaO3Molecular weight:100.09Melting point:825 °CPH value:9.91Storage Conditions:Store at +5°C to +30°CCertificationsPackaging & Shipping
