Product name: High purity reagent grade calcium montmorillonite:
It is made of high quality natural white bentonite ore as raw material, through unique preactivated, pulp, stripping dispersion and wet purification process. Product as a white powder, non-toxic, tasteless, analysis shows its purity is over 99.0%, the total amount of heavy metals is less than 10ppm, arsenic content is less than 2ppm,the X- ray powder diffraction (XRD) shows d(001)= 1.450-1.550nm and d(060)= 0.1490-0.152nm, free of quartz, feldspar, cristobalite and kaolin. Instructions for use: High purity reagent grade montmorillonite is a tiny crystal nanostructures consisting of 2: 1 type layered aluminosilicate mineral.The crystal structure character indicates it is a typical two-dimensional of mineral materials in the nature.The special crystal structure and having ion-exchange make it have good dispersion, thixotropic, suspension and other properties in an aqueous system.It is widely used in pharmaceutical and scientific fields. For example it currently is used as pharmaceutical standards, in research and development, catalysts, nano plastics, nano antibacterial material, nano-porous material etc. Specification: Properties: White powder Montmorillonite content,%: ≥99.0 The total amount of heavy metals, ppm: ≤10 Arsenic, ppm: ≤2 Loss on drying,%: ≤10 Soluble substances in water,%: ≤0.5 Chloride,%: ≤0.025 Carbonate: not detected PH: 7.0-8.0 |
