Description
The effect of parameters involved in the sol-gel preparation of the monolithic porous ZrO2-SiO2 glasses on the pore characteristics has been investigated. Followings have been obtained.<br>(1) A high hydrolysis temperature seemed to be favored to form large micropores in the resultant glasses.<br>(2) The surface area (SSA), pore volume (PV) are decreased by increasing heating temperature, while mean pore radius (MPR) remained almost unchanged.<br>(3) The influence of the content of HCl used as a catalyst was most remarkable. As the HCl content becomes higher, the larger MPR resulted.<br>On the basis of above results, the porous monolithic ZrO2-SiO2 glasses containing ZrO2 up to 14.4mol% have been made via sol-gel reaction at 80°C using h-value as high as 0.5, i-C3H7OH as a solvent. The pore size as large as 40-60Å in diameter, SSA and PV ranging from 450 to 550m2g-1 and 0.4 to 0.7ml·g-1, respectively, have been attained. Those glasses are highly alkaline-resistant compared to the porous SiO2 glass.
