Abstract
A method for making a mono-dispersed metal titanate includes the steps of: (a) mixing titanate ester, metal salt, and rare earth metal salt in a molar ratio of 1:1:x in a reaction medium comprised of ethanol and water to form a solution, wherein x is in the range from 0 to 0.1; (b) heating the solution, under an alkaline condition to form a white sediment; (c) filtering out liquid part of the solution to obtain the white sediment, (d) washing the white sediment, and (e) drying the white sediment to obtain mono-dispersed metal titanate.
