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60～100 nm.
The boehmite(γ-AlOOH)sol dcrived from aluminium isopropoxide(Al(OC3H71)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 60～100 nm.
