Abstract:
The synthesis of Lithium Magnesium silicate, the preparation and application of Lithium Magnesium silicate were reviewed. Synthetic synthesis of Lithium Magnesium silicate mostly uses hydrothermal method and microwave method. Lithium Magnesium silicate can be organically modified by in situ method, ion exchange method or adsorption method. After organic modification, the interfacial properties of Lithium Magnesium silicate changed from hydrophilic to lipophilic, and the dispersibility in organic medium was improved. Organically modified lithium magnesium silicate can be used as an adsorbent for the treatment of wastewater contaminated by heavy metal ions or dyes, preparation of polymer/Clay composites, preparation of catalysts, catalyst carriers, etc. With the rapid development of organic-inorganic nanocomposites, the organic modification of Lithium Magnesium silicate has been widely concerned by scholars at home and abroad.Key words:

Abstract:
In this paper, a kind of magnetorheological fluid with good stability was prepared from nano lithium magnesium silicate, carbonyl iron powder, silicone oil and other raw materials. The magnetic properties, surface morphology and particle size of carbonyl iron powder were measured by vibrating sample magnetometer, scanning electron microscope and specific surface analyzer, respectively; the apparent viscosity and magnetic shear stress of magnetorheological fluid were measured by magnetic rheometer. The sedimentation stability of magnetorheological fluid was analyzed by static sedimentation method. The results show that the nano-Lithium Magnesium silicate has a good function of adjusting the viscosity, and the magnetorheological fluid prepared by the Nano-Lithium Magnesium silicate has thixotropy, sedimentation resistance and greater magnetic shear stress; the quantitative relationship between the concentration of nano lithium magnesium silicate and the viscosity and magnetic shear stress of magnetorheological fluid was obtained.

Abstract:
The invention provides a method for synthesizing magnesium silicate lithium montmorillonite by directly using salt lake brine. The method is to add soluble silicate to Salt Lake concentrated brine, adjust the pH value of the mixed solution with alkali solution to not less than 11, and adjust the stoichiometric ratio of magnesium, lithium and silicate in the mixed solution with primary magnesium product and primary lithium product, and then place the mixed solution in a high-pressure reaction kettle, under the condition of high pressure hydrothermal reaction, after cooling, centrifugal washing or Suction filtration, drying to obtain lithium magnesium silicate powder. The invention uses lithium and magnesium resources rich in Salt Lake Resources to synthesize lithium magnesium silicate, the synthesis process does not require separation of magnesium and lithium, avoids the technical problem of separation of magnesium and lithium, has simple process, short production cycle and low cost, high added value of the product, suitable for industrialization; The raw materials of the invention are non-toxic, harmless, no pollution in the process, and no waste is generated, which is beneficial to the comprehensive development of Salt Lake Resources
