Abstract

The invention discloses a microwave synthesis method of lithium magnesium silicate. The method comprises the following steps of adding water to magnesium oxide, lithium carbonate and white carbon black so that the magnesium oxide, the lithium carbonate and the white carbon black are dissolved, adjusting a pH value to 10-15, and performing a microwave (2000-3000MHZ) reaction in a reaction kettle for 6 hours; and then performing heating (200-260 DEG C), performing a reaction at high pressure (2.0-2.6MPa) for 7 hours, performing washing after cooling, performing drying and performing crushing so as to obtain lithium magnesium silicate products. The method is simple in technology, short in production time, and low in cost, granularity of finished products is uniform, the stickiness is high, the transmittance is high, and the microwave synthesis method of the lithium magnesium silicate is suitable for industrialized production, and non-toxic, harmless and pollution-free.

Description

technical field [0001] The invention relates to a microwave synthesis method of lithium magnesium silicate, which belongs to the technical field of chemical industry. Background technique [0002] Lithium magnesium silicate has excellent properties such as thickening, dispersion and adsorption, and is widely used in daily chemical, catalysis, coating and other industries. Natural lithium magnesium silicate resources are extremely scarce, and contain certain impurity minerals, which affect its use. Lithium magnesium silicate for industrial use is mainly obtained through artificial synthesis. At present, the artificial synthesis of lithium magnesium silicate is mainly carried out by hydrothermal method, and the silicate used is mainly sodium salt and potassium salt, which has high cost, insufficient reaction, and uneven product. The main components of white carbon black are silicon dioxide, calcium silicate, and aluminum silicate. It has a large output in my country and the ...
