Ultra-fine calcium carbonate is the primary particle size between 0.02-0.1μm in calcium carbonate, first developed out of Japan, is one of the most inexpensive material, it has the special quantum size effect, small size effect , surface effect, as compared to conventional powder in the reinforcement, transparency, decentralization, thixotropy and leveling, etc. have shown a clear advantage, especially in active calcium carbonate, packed with features characteristics, which greatly broadens the scope of its application, the toughening and strengthening effects greatly improve and enhance the performance of related industries and quality.

Ultra-fine calcium carbonate can be used as high-end cosmetics, soap, facial cleanser, such as children's toothpaste filler. Ultra-fine calcium carbonate in industry is an important medium composition and source of calcium additives, as a buffer and applied to microbial fermentation production of antibiotics, analgesics and in the stomach also play a pharmacological effect.

In addition, the rubber with ultra-fine calcium carbonate, the higher the value of the absorption of oil, calcium carbonate for rubber reinforcement and infiltration of the better, through the application found in the different morphology of ultra-fine calcium in order to chain-like ultra-fine calcium carbonate the best reinforcement of rubber.

China's plastics industry is the industry's largest users of ultra-fine calcium carbonate is one of the more mature field of applied technology. Ultra-fine calcium carbonate to increase the volume of plastic products, reduce costs, improve stability, hardness and rigidity, improved processing properties of plastics to increase their heat resistance, improved plastic astigmatism, scratch resistance, smoothness, and on the gap the toughening effect and impact strength in the mixing process and other aspects of viscous flow have significant results.

Printing ink market demand ultra high performance calcium carbonate. Ultra-fine calcium carbonate for printing ink products show excellent dispersion, transparency, excellent gloss and hiding power, and excellent ink absorption and drying. Ultra-fine calcium carbonate for printing ink must be activated, spherical or cubic crystal form. Most of the current use of high-grade ultra-fine calcium carbonate filler ink.
