Ultrafine powder grinding

The key technical specifications of ultrafine calcium carbonate—particle size, specific surface area, crystal form, and oil absorption—directly impact its application performance. While other indicators are important, they are relatively easy to achieve industrially. For specialized products, different applications place varying emphasis on various indicators and require different requirements. Particle Size and Specific Surface Area The […]

Driven by global energy transition and “dual-carbon” strategies, lithium-ion batteries are core components of electric vehicles and energy storage systems. Their performance improvement and cost reduction are key industry priorities. Negative electrode materials, the “energy heart” of lithium batteries, determine capacity, cycle life, and safety. Traditional graphite anodes, nearing their 372 mAh/g capacity limit, cannot

Matting calcium carbonate generally refers to calcium carbonate products used for matting purposes. Its main function is to adjust the gloss of material surfaces, making them appear low-gloss or matte. Characteristics Excellent matting performance Uniform particle size Good chemical stability High whiteness Applications Coatings industry Plastics industry Paper industry Other industries It also has applications

Calcium carbonate (chemical formula: CaCO₃) is a non-toxic, odorless, and tasteless inorganic compound. It is also known as limestone, calcite, marble, or chalk.As one of the most common minerals on earth, it exists widely in rocks (such as limestone and marble) and in biological skeletons and shells. Calcium carbonate is divided into three main categories:

The average primary particle size of superfine calcium carbonate should be 0.02–0.1 μm. This is a basic requirement. Otherwise, it cannot be called “ultrafine.” However, this is only half the task. If surface treatment and dispersion technology are insufficient, the primary particles will agglomerate into secondary particles hundreds of nanometers in diameter. Transmission electron microscopy

Calcium carbonate is the most widely used extenders in coatings, known for improving coating properties. With the rapid development of the coatings industry, the demand for calcium carbonate powder is growing, and the quality requirements are becoming more strict and diversified. Dope calcium carbonate has emerged as a key ingredient in enhancing the performance of

Now, the tire’s airtight rubber mainly uses light calcium carbonate to bulk. The raw material of heavy calcium carbonate is widely available and cheaper. Also, technology has made heavy calcium carbonate finer. Recently, researchers have studied using heavy calcium carbonate in rubber. For example, changing the surface of calcium carbonate affects rubber composites. It affects
