Abstract：

Using Al2O3 sol and ZrO2 sol with different molar ratio(r),Al2O3-ZrO2 composite membranes were prepared by sol-gel method.The results of the characterized analysis which use testing instruments such as Ukrainian viscosity,thermogravimetric(TG-DTG),Fourier transform infrared(FT-IR),X-ray diffraction(XRD),scanning electron microscope(SEM),nitrogen adsorption-desorption method to analyze thermal stability,crystal phases,surface morphology,specific surface area and pore structures of Al2O3-ZrO2 composite membranes demonstrate that:lake this,the composite sol of different molar ratio is an important factor affecting the viscosity of Al2O3-ZrO2 composite sol,with the increase of r,the viscosity of the composite sol decreases and the cracking degree decreases gradually;At the same heat treatment temperature of 800 ℃,the main crystal phase is t-ZrO2 and Al2O3 sol content in the composite membranes inhibited the crystallization and transparency of ZrO2 grains;When composite sol of r=1,the Al2O3-ZrO2 Composite sol is clear and transparent as well as it’s no cracking after drying,the viscosity was 2.65 mPa·s.The prepared Al2O3-ZrO2 composite membrane had a good thermal stability,compact structure,narrow pore size distribution,the grain size is 31.30 nm.The specific surface area and average pore diameter are 84.98 m2/g and 9.75 nm respectively.
