用青海柴达木盆地的盐湖卤水为原料,经浓缩后用水热法直接合成球形纳米硅酸镁锂,此方法充分利用了盐湖资源,无需镁锂分离。同时对样品进行了X-ray、TEM表征、计算了比表面积和粒径。 Saline lake brine from Qaidam Basin in Qinghai Province was used as raw material. After concentration, spherical magnesium silicate lithium silicate was directly synthesized by hydrothermal method. This method made full use of salt lake resources without separation of magnesium and lithium. At the same time, the samples were characterized by X-ray and TEM, and the specific surface area and particle size were calculated.
