Abstract

Titanium hydrogels prepared without and with different amounts of surfactant (sodium dodecylbenzene sulfonate) have been examined for their behavior during aging for more than 100 days (some for more than 200 days) at different temperatures. By means of XRD semi-quantitative analyses and SEM observations with high magnification (100 K), the effects of the surfactant on the crystalline structure and content, on the morphology and the size of the particles, and on the aggregation phenomena have been investigated. It was also found that aging somewhat decreases the adsorption capacity of the gels.
