Popis:	Al2O3-SiO2-ZrO2 composite sol was prepared with aluminum nitrate, zirconium oxy-chloride, etc as precursors, by which Al2O3-SiO2-ZrO2 composite ceramic microfiltration membrane was achieved. Stable boehmite sol can be obtained by adding Al(NO3)3 into ammonia but not the reverse. The stability of the composite sol depends on the ratio of Si/Zr. The aperture of the composite membrane can be micron level. It has good effect on sewage treatment.
