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,

Calcium carbonate is an inorganic compound with the chemical formula CaCO3. In nature, calcium carbonate has multiple identities, including calcite, limestone, marble, white marble, chalk, stalactites, travertine, etc. It is also the main component of corals, shells, eggshells, etc. Calcite Calcite is the most common calcium carbonate mineral in nature. It’s one of the identities

For ultrafine calcium carbonate, particle size, specific surface area, crystal form, and oil absorption value are the most important technical indicators, directly affecting its application performance. Of course, this does not deny the importance of other indicators; it’s just that other indicators are relatively easier to achieve in industrial applications. However, for specialty applications, different

Anode materials are crucial for lithium-ion batteries and directly affect battery performance. Graphite, the most used carbon-based anode, has low capacity and poor stability. Its safety and rate performance are hard to improve.Finding new carbon-based materials to replace commercial anodes is a research focus.Among carbon materials, porous carbon has high surface area and controllable morphology.
