Summary:PROBLEM TO BE SOLVED: To provide an amorphous aluminosilicate particle powder high in a polar gas adsorption amount per unit area, a production method thereof, a slurry, and a molded article.SOLUTION: Provided is an amorphous aluminosilicate particle powder having a BET specific surface area of 400 to 1,000 m/g and a bulk density (ρa) of 0.30 to 0.80 g/cm. A method for producing the amorphous aluminosilicate particle powder is provided which comprises subjecting a slurry having undergone an aging reaction and a hydrothermal reaction to water-washing and concentration in order for the slurry to have a concentration controlled to 200 to 400 g/L and thereafter drying the slurry.SELECTED DRAWING: None 【課題】 本発明は、単位体積当たり、極性ガス吸着量が高い非晶質アルミノケイ酸塩粒子粉末、及びその製造方法、スラリー並びに成形体を提供するものである。【解決手段】 ＢＥＴ比表面積が４００〜１０００ｍ２／ｇの非晶質アルミノケイ酸塩粒子粉末であって、嵩密度(ρａ)が０．３０〜０．８０ｇ／ｃｍ３であることを特徴とする非晶質アルミノケイ酸塩粒子粉末。熟成反応、水熱反応後のスラリーを水洗・濃縮することにより２００〜４００ｇ／Ｌの濃度に調整後、乾燥することを特徴とする非晶質アルミノケイ酸塩粒子粉末の製造方法。【選択図】 なし
