Nano magnesium lithium silicate, carbonyl iron, silicon oil, as the raw material for preparing a good stability of MRF. Using a vibrating sample magnetometer (VSM), scanning electron microscopy, surface area analyzers were tested carbonyl iron magnetic properties, surface morphology and particle size; with a magnetic rheometer MRF apparent viscosity and magneto shear stress; standing by sedimentation analysis settling stability MRF. The results showed that: nano magnesium lithium silicate having a good viscosity regulation, thixotropic MR fluids for their preparation, anti-settling, the greater the induced magnetic shear stress; obtained nano-lithium silicate concentration magnetorheological fluid viscosity and magneto-quantitative relationship between shear stress.

Study of a synthetic smectite clay minerals - magnesium lithium silicate, elaborated structure, characteristics and mechanism of the material. The analyzed tests showed that a 2% aqueous dispersion viscosity up 5Pa.s above, thixotropic rheological properties of a typical system, the thixotropic index (TT)> 10. gum hectorite and organic thickeners such as CMC when used in conjunction with a synergistic thickening effect, can reduce the total amount of thickener the stable rheological properties, biological stability, good temperature stability, overcomes some of the limitations of the application of organic thickener is introduced in an aqueous colloid of lithium silicate paint (latex) use of methods, dosage and application points, applications include test examples.

Synthetic hectorite, preparation and application of organic magnesium lithium silicate were reviewed. Synthetic magnesium silicate lithium mostly by hydrothermal method and microwave method. Situ method, ion exchange or adsorption can be organically modified hectorite. The organic lithium magnesium silicate modified by the interfacial properties of hydrophilic to lipophilic, in an organic dispersion medium is improved. Organically modified hectorite may be used as sorbents for treating heavy metal ions or dyes contaminated waste water, preparation of the polymer / clay composite material, preparation of the catalyst, catalyst carrier. As the organic - the rapid development of complex inorganic nanomaterials, organic modified silicate of lithium has been widespread concern of scholars.
