以无机盐为原料制备钇稳定的氧化锆超滤膜
Preparation of Yttria Stabilized Zirconia Ultrafiltration Membranes with Inorganic Precursors
摘要
Abstract
Yttria stabilized zirconia (YSZ, 8% mol Y2O3) membranes with expected composition were coated on porous alumina substrates by a dip-coating process with YSZ sol, which was prepared by sonicated dispersing YSZ powder in ethanol. The YSZ powder was synthesized by co-precipitation from inorganic aqueous solutions of ZrOCl28H2O and Y(NO3)36H2O, followed by azeotropic distillation and sintered at 600C for 2h. Crystalline structure of the YSZ powder was characterized by X-ray diffraction. Particle size of the sol was determined by laser scattering measurement. The mean pore diameter of an unsupported YSZ membrane was about 6nm as investigated by nitrogen isothermal desorption measurement. Investigation with scanning electron microscopy and nitrogen permeation testing showed that the membranes were crack-free关键词
