Sd0107 high purity (reagent grade) montmorillonite is one of the two octahedral high purity calcium montmorillonite products jointly developed by China University of Geosciences (Wuhan) nano center and Zhejiang sanding Technology Co., Ltd. It uses high-quality natural white bentonite as raw material and is refined by a unique wet purification process, such as pre activation treatment of beneficiation, pulping, flaking and dispersion, ultra-fine classification, etc. The product is white powder, nontoxic and tasteless. The purity of montmorillonite is more than 99.0%, the total amount of heavy metal is less than 10ppm, the arsenic content is less than 2ppm. The D (001) is 1.450-1.550nm, D (060) is 0.1490-0.152nm by X-ray powder diffraction. It does not contain quartz, feldspar, quartz, kaolin and other impurities.

【Use description】

Sd0107 high purity (reagent grade) montmorillonite is composed of nanostructured micro crystals with a ratio of 2:1 Montmorillonite is a typical two-dimensional nano mineral material in nature. It has special crystal structure and ion exchange property. Its good dispersibility, thixotropy, suspension and other properties in water system make it widely used in medicine, scientific research and other fields. At present, sd0107 high-purity (reagent grade) montmorillonite is only used in medical enterprise montmorillonite drug standard products, scientific research and teaching in Colleges and universities and scientific research institutes, catalysts, nano plastics, nano antibacterial materials, nano porous materials and other high value-added fields due to its high classification precision, complex production process, high technology content and high production cost.
