Microwave synthesis method of lithium magnesium silicate

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. 本发明公开了种硅酸镁锂的微波合成方法。该方法是将氧化镁、碳酸锂和白炭黑加水溶解，调节p
