Magnesium carbonate comes in three main forms: light magnesium carbonate, spherical magnesium carbonate and transparent magnesium carbonate, which have different uses in industry and everyday applications.
Light Magnesium Carbonate
Light magnesium carbonate is a common inorganic compound with high whiteness and purity, usually in the form of a white powder. Its main uses include:
- Manufacture of rubber, plastics, paints, coatings, inks and other products: as a filler and thickener to improve the physical properties of products.
- Manufacture of fireproof materials: used in the manufacture of fireproof boards, heat insulation boards, etc., with good heat insulation, sound insulation and fireproof performance.
- Pharmaceutical industry: used in the preparation of antacid, stomach powder and other drugs.
- Food industry: as flour improver, improve the dispersion and fluidity of flour.
Spherical magnesium carbonate
Spherical magnesium carbonate has good filling, dispersibility and fluidity, mainly used in:
- Rubber and plastic products: as filler and reinforcing agent, to improve the tensile strength and abrasion resistance of products.
- Paints and coatings: as a filler to improve the performance of products.
- Toothpaste and cosmetics: as additives to improve the quality and stability of products.
- Pharmaceutical industry: used in the preparation of various drugs.
Transparent magnesium carbonate
Transparent magnesium carbonate has fine particles and uniform particle size, with the following main characteristics:
- Rubber products: used as filler and reinforcing agent for transparent or light-colored rubber products, enhancing the abrasion resistance and tensile strength of rubber.
- Paints and coatings: as additives to improve the performance of products.
- Toothpaste and cosmetics: as additives to improve the texture and stability of products.
- Pharmaceutical industry: used in the preparation of medicines.
Comparison of production methods and application areas of different forms of magnesium carbonate
- Light magnesium carbonate: mainly produced by dolomite carbonization method, the raw material is easy to get and the cost is low, widely used in rubber, plastic, paint, coating, medicine and other industries.
- Spherical magnesium carbonate: prepared with soluble magnesium salt and carbonate as raw materials, higher production cost, but good filling and dispersion, suitable for high-end products.
- Transparent magnesium carbonate: fine particles, suitable for filling and reinforcing transparent or light-colored products.
