Abstract: Microstrucutre of Al2O3 xerogels and aerogels pre pared from aluminum-tri-sec-butoxide (Al(O-sec-Bu)3) modified with ethylacetoacetate (EAcAc) was investi gated for controlling the microstructure of Al2O3. The specific surface area and the pore volume of heat-treat ed xerogels decreased with an increase in the EAcAc/ Al(O-sec-Bu)3 molar ratio, whereas the size of pores was not affected by the ratio. The specific surface area of aerogels decreased monotonously with an increase in the heat-treatment temperature …
