Zusammenfassung:	PROBLEM TO BE SOLVED: To provide boehmite in which the high decomposition temperature of boehmite is held, and whose chargeability is increased, and a method for producing the same.SOLUTION: Provided is boehmite highly charged by pulverization treatment, and being highly chargeable boehmite in which specific surface area is 105 to 300% of the boehmite not subjected to the pulverization treatment. Alternately, provided is boehmite highly charged by pulverization treatment, and in which oil absorption in accordance with JISK5101 is 97% or lower of the boehmite not subjected to the pulverization treatment. Also provided is a method for producing the highly chargeable boehmite in which a media source is used for the pulverization treatment. 【課題】ベーマイトの高い分解温度が保持され、かつ充填性が高められたベーマイト及びその製造方法を提供すること。【解決手段】本発明は、粉砕処理により高充填化されたベーマイトであり、比表面積が粉砕処理されないベーマイトの１０５％〜３００％の高充填性ベーマイトである。本発明は、粉砕処理により高充填化されたベーマイトであり、ＪＩＳＫ５１０１に準拠する吸油量が粉砕処理されないベーマイトの９７％以下の高充填性ベーマイトである。本発明は、粉砕処理にメディア媒体を使用する前記の高充填性ベーマイトの製造方法である。【選択図】なし
