Exploitation of the Sol-Gel Route in Processing Ceramics and Composites
Abstract
The sol-gel process for making ceramic powders from solutions-gels, and especially the use of alkoxide precursors, and their subsequent conversion of gels to ultrahomogeneous glass was developed at Penn State by the P.I. and his students. Our conceptual innovation on which the present work rests is, we believe, as major a development as was our development of the sol-gel processing in the decade 1948-58. In that development we succeeded in making ceramics that were homogeneous on the 'unit cell' scale. Since 1982 we conceived and first published and filed patents on and what we have now developed in detail is deliberate heterogeneity on the same scale (1-10 nm units). The work under this grant is focused on applications and processing, while the thermodynamics and structure of this family of heterogeneous materials is studied under a parallel NSF grant. (JG)
