Effect of aging time and concentration of aging solution on the porosity characteristics of subcritically dried silica aerogels

Smitha, S; Shajesh, P; Aravind, P R; Rajesh Kumar, S; Krishna Pillai, P; Warrier, K G K (Elsevier, 2006)

Subcritical drying technique has emerged as effective and convenient method for the synthesis of silica aerogels compared to the conventional supereritical route. One of the important steps in this method is aging of the ...
Mesoporous silica-alumina aerogels with high thermal pore stability through hybrid sol-gel route followed by subcritical drying

Aravind, P R; Mukundan, P; Krishna Pillai, P; Warrier, K G K (Elsevier, 2006)

Silica-alumina mixed oxide aerogels have been synthesised for the first time by subcritical method, having compositions of 5, 10, 15, 20 and 25 wt.% of alumina in silica through a hybrid sol-gel technique. Boehmite was ...
