Limestone is a common non-metallic mineral and a valuable resource with wide applications. Limestone is the commercial name for the mineral raw material of limestone rock. Throughout human history, limestone has been widely used due to its wide distribution and easy accessibility in nature. In modern industry, limestone is the main raw material for manufacturing […]

Nano calcium carbonate refers to calcium carbonate microparticle aggregates with a particle size between 1-100 nm. Particle size reduction alters the crystal structure and surface electronic structure. This creates surface effects, size effects, and macroscopic quantum tunneling effects not present in larger particles. Production Currently, carbonation is the main method for industrial production of nano-calcium

Calcium carbonate is a non-toxic, tasteless, and non-irritating white powder. It is one of the most widely used inorganic fillers. Calcium carbonate is neutral, insoluble in water, but soluble in acids. Based on production methods, it can be divided into heavy calcium carbonate, light calcium carbonate, colloidal calcium carbonate, and crystalline calcium carbonate. Calcium carbonate

There are many types of ground calcium carbonate grinding and processing equipment. They are combined with ultra-fine grade machines to create an ultra-fine processing system. This system generally achieves the desired effect of ultra-fine production. Currently, the mainstream demand for heavy calcium products is between 600 and 1500 mesh. Compared to talc, barite, and kaolin,

15-17 May, Shenzhen World Exhibition & Convention Center, Booth No. :3T159-1 The China International Battery Fair (CIBF), organized by the China Chemical and Physical Power Sources Industry Association, is the largest international event in the battery industry. It includes a series of activities such as exhibitions, technical conferences, information release sessions, and business negotiations. It

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
