摘　　要：以异丙醇铝为先驱体，采用Yoldas方法成功地制备了勃姆石（γ—AlOOH）溶胶；并采用XRD、FTIR、UV—Vis分光光度计和TEM测试技术对勃姆石溶胶进行表征。研究结果表明，制备所得的勃姆石溶胶稳定、透明，溶胶粒子结晶性好，形貌呈纤维状，长度大约为60～100nm。The boehmite （γ-A1OOH） sol derived from aluminium isopropoxide （Al（OC3H7i）3） was prepared by the Yoldas method. The characteristics of the boehmite sol were investigated by X-ray diffraction （XRD）, fourier transform infra-red spectrum （FTIR）, UV-Vis transmission （UV-Vis） and transmission electron microscope （TEM）. The results show that the as-prepared boehmite sol is a stable, transparent sol and the sol particles has well crystallinity and fibrillar shape with the size of 60~ 1 O0 nm
