Abstract : Hydrolysis of metal alkoxides results in the formation of polymer molecules with oxide main chains framed by hydroxyl and organic groups. The skeleton of the main structural chains in these polymer molecules is generally analogous to the skeleton of fused silica and quartz. However the method of hydrolysis affects the nature and extent of the oxide network. Thus changes in the hydrolysis process alter many of the fundamental properties of the gel which are reflected in its general behavior, as well as the oxide materials derived from the gel. One of the critical factors affected by the method of hydrolysis is the capability of the gel to remain monolithic through pyrolysis. This report presents an investigation of various parameters involved in the formation of inorganic polymers from metal alkoxides and the structures of these oxide materials. (Author)
