• The β-spodumene(Li_2O・Al_2O_3・4SiO_2, LAS)powders were prepared by the sol-gel process using a mixture of silica sol, alumina sol and lithium nitrate solution. Si(OC_2H_5)_4, Al(OC_4H^<sec>_9)_3 and LiNO_3 were used as the starting compounds. Thermogravimetric and differential thermal analyses(TG/DTA), X-ray diffraction(XRD), Fourier transform infrared spectroscopy(FT-IR), wavelength-dispersive spectroscopy(WDS), transmission electron microscopy(TEM)and electron diffraction(ED)analysis were utilized to characterize the β-spodumene powders prepared by the sol-gel process. The crystallization temperature of the LAS gel powder estimated by TG/DTA was about 630°C. When the LAS dried gel was heated from 600 to 850°C, the crystallized powders of the single phase β-spodumene were obtained.
