In this article, the methods of lithium salt and potassium salt were used to synthesize LiSb(OH)6. Meanwhile, LiSbF6 was also prepared by the methods of neutralized dissolution and hexafluoroantimonic acid. The relative contents of Li, Sb, and F in LiSb(OH)6 and LiSbF6 were determined, and the results showed these values were extremely similar to the theoretical values. The phases of the products were detected by x-ray diffraction, and the results indicated they were single-phase products with good crystallinity. The morphologies of the products were characterized by scanning electron microscope, which revealed the LiSb(OH)6 crystals were hexagonal layered structures. The infrared spectra of the LiSbF6 crystals proved the presence of SbF6 in the crystals. Moreover, the result of the thermal stability test indicated that the initial decomposition temperature of LiSbF6 was 367.64°C. Therefore, these novel methods can be used as a reference to effectively improve the traditional processes for LiSb(OH)6 and LiSbF6 preparation.
