An aluminum hydroxide having high purity with high brightness and a method for producing such an aluminum hydroxide are provided. The aluminum hydroxide may be produced by a method which comprises the steps of mixing a crude aluminum hydroxide with an alkaline solution to obtain a mixture thereof; heating the mixture to obtain a slurry in which a solid of aluminum hydroxide is present in an amount of from about 10% by weight to about 90% by weight based on the crude aluminum hydroxide to be used for the mixing; cooling the slurry to precipitate an aluminum hydroxide; and separating the resulting aluminum hydroxide from the slurry.
