국내산 Kaolinite로부터 중기공성 γ-알루미나의 제조
Preparation of Mesoporous γ-Alumina from Domestic Kaolinite
The mesoporous γ-Al2O3 prepared by elective leaching of calcined domestic kaolinite has been studied. γ-Al2O3 prepared from kaolinite calcined at 950℃ for 24hrs followed by leaching with 1-4 mole KOH solutions at 50-90℃ for 1hr had specific surface areas as high as 150-250㎡/g and average pore diameter of 65Å. The specific surface areas and total pore volumes increased gradually with temperature and concentration of KOH solution.
