Heavy calcium carbonate, also known as heavy calcium, is a colorless, tasteless white powder. It is almost insoluble in water and alcohol, but reacts with dilute acetic acid, hydrochloric acid, and nitric acid. It fizzes and dissolves when exposed to these acids. When heated to 898°C, it decomposes into calcium oxide and carbon dioxide. The […]

Calcium carbonate is an excellent filler, with white color, pure quality, and high coloring ability. It has stable chemical properties, low cost, and adjustable particle size and shape. With these advantages, it has successfully entered many industries such as rubber, plastics, PVC cables, and high-grade coatings. From construction materials to food, pharmaceuticals to textiles, it

Papermaking uses wood, reed, bagasse, straw, wheat straw, cotton stalks, hemp stalks, and cotton as raw materials. It produces pulp and then transforms the pulp into paper and paperboard. Papermaking involves beating the pulp, sizing, adding fillers, and other treatments. It is a complex process to form paper with various properties. Why do we need

Calcium is an essential element for the human body. It helps maintain osmotic pressure and acid-base balance. It plays a key role in various physiological and biochemical processes.In recent years, calcium carbonate has been widely used in food. It is added to meet the body’s calcium needs. Calcium carbonate serves as a supplement, leavening agent,

Activated calcium carbonate, also known as modified calcium carbonate, surface-treated calcium carbonate, colloidal calcium carbonate, or Bai Yanhua, is commonly referred to as “active calcium.” It is made by modifying light or heavy calcium with surface modifiers. This process alters crystal form, particle size, distribution, and surface properties. As a result, modified calcium carbonate gains

Calcium carbonate is an important chemical material with rich resources. It features simple production and excellent performance. It is widely used in rubber, ink, medicine, and food. In the medical field, its use is even more extensive.Calcium carbonate is an excellent calcium additive and supplement. Calcium-based supplements offer high calcium content and absorption. They also

Calcium carbonate powder surface modification alters surface or interface using physical, chemical, or mechanical methods. It purposefully changes the powder’s surface physical and chemical properties. These include surface energy, wettability, electrical properties, adsorption, and reactivity. It also affects surface structure and functional groups. This meets the needs of modern materials, processes, and technologies. The role

Heavy calcium carbonate is a powder material made from limestone, chalk, marble, and other ores. It is produced by mechanical grinding methods. It has wide raw material sources, high whiteness, low oil absorption, and good applicability. It is low-cost and the most widely used inorganic non-metallic mineral powder product. Currently, the fine processing technology of

Calcium carbonate is an inorganic compound with the chemical formula CaCO₃. It is commonly known as limestone, limestone, stone powder, marble, etc. It is alkaline, basically insoluble in water, and easily soluble in hydrochloric acid. It is one of the most common substances on earth and exists in rocks such as aragonite, calcite, limestone, marble,
