| Abstract: | Fiber-like nano-magnesium hydroxide was prepared from bittern, after extraction of sodium and lithium. The bittern was removed of calcium, precipitate magnesium during 20~ 30 ℃ in the presence of complex dispersant ammonia solution, and then aged at 50℃. The product was analyzed and characterized by X-ray diffraction (XRD), X-ray fluorescence spectrum (XRF), inductive coupled plasma emission spectrum (ICP), scanning electron microscope (SEM) and transmission electron microscope (TEM). |
