Electron Microscopy of Modified Aluminum Alkoxide Microstructures on Freeze-Drying


Direct imaging of microstructures in chelated aluminum alkoxide systems subjected to freeze-drying and freeze-thaw-drying is reported using cryo-scanning electron microscopy (SEM) and SEM techniques. Aluminum sec-butoxide was chelated with a beta-diketoester in different molar ratios. This system was gelled by hydrolysis under intense sonication. The… (More)
