Effects of synthesis parameters towards morphology & physical characteristics of silica materials
This study investigated the effects of synthesis parameters such as water to alcohol (water/alcohol) ratios, types of alcohol and catalysts towards morphological properties of silica xerogels which were prepared according to stober and conventional methods. The morphological properties of silica xer...
