This work represented a continuation of our efforts directed to understanding the microstructure of epoxy resin cured with amine hardeners. The focus has been on characterizing a series of networks formed by changing the formulations and the processing conditions of the system. The table on pages shows the Epon 828 epoxy/triethylene tetramine (TETA) formulations which were explored, together with the curing conditions employed. Ceramics from Organo-metallic Precursors: Our investigations of the conversions of organo-metallic precursors to ceramics have directed attention to five principal areas. These were: 1) Investigation of hydrolysis and condensation kinetics of tetratethylorthosilicate (TEOS), an important precursor for many glasses and ceramics; 2) Exploration of the competition between crystallization and viscous sintering, to determine the conditions under which dense glassy bodies or coatings can be obtained; 3) Investigation of the hydrolysis and condensation of tantalum ethoxide to form coatings of tantalum oxide; 4) Initial exploration of organic modified as novel coatings and bulk materials; and 5) Exploration of the conversion of aluminum alkoxides, most notable aluminum sec butoxide, to aluminum oxide. Progress in the first two of these areas will be described in the present report; progress in the last three will be deferred to a later date.
