Theory and method of application-oriented ceramic membranes design (III) Optimization and preparation of ceramic membrane for filtration of titania suspension

On the basis of the developed microfiltration model, membrane pore size was optimized to filter the particle suspensions of titanium pigment. The optimized Al₂O₃ ceramic membrane was prepared by state particle sintering method and characterized by SEM and the gas bubble pressure method. The prepared membrane was superior to commercial membranes and the model calculation showed good agreement with the experimental results. The method of application-oriented ceramic membranes design was basically completed.
