PURPOSE:To obtain the titled slurry, containing a specific amount of an aluminum salt and having excellent dispersibility in a small amount of a solution. CONSTITUTION:(A) Fine particulate alumina having >=1m<2>/g specific surface area is added to a solution prepared by adding and blending (B) an aluminum salt, e.g. AlCl3, expressed by the formula (X is monovalent anion such as NO3<->, Cl<->, etc.) in an amount of 0.005-1wt% (expressed in terms of oxide) based on the component (A) with (C) a dispersion medium, e.g. water or alcohol, etc., so as to provide 0.01-0.2wt% concentration. |
