This paper has researched the best optimum ratio of alumina silicate fiber and silica sol in ceramic fiber filters. Then we will use porosity, aperture size, compressive flexural strength and SEM to evaluate different ratios and different technological parameters, which have effect on the properties of fiber filters. It was found that, the best ratio is silica sol content of 68wt%, alumina silicate fiber content of 12wt% and water content of 20wt%. In addition, we choose 0.08MPa and 5min as the best technological parameters for vacuum forming.
