Abstract:

The major challenge facing sol-gel processing of advanced materials, and in fact the entire field of chemically derived ceramics, is to relate processing variables to final properties. In order to develop fundamental processing-properties relationships it is essential to characterize the material after each step of the process mixing, aging, drying, stabilization and densification. Fundamental studies of sol-gel processing science have led to two major accomplishments 1 Development of a generic sol-gel process for producing fully dense silica monoliths termed GELSIL, and 2 Identification of the need for a broad range of characterization methods to apply to processing steps. In order to achieve the production of reliable and reproducible sol-gel monoliths, a series of seven tasks have been identified. These tasks and a summary of results to date are given below Sol-Gel Processing Science for Continuous Optics Processing Fabrication Science for Net Shape Precision Optics Effects of Ultrastructure on Thermal and Mechanical Properties of Sol-Gel Optics Effects of Ultrastructure on the Optical Properties and Optical Homogeneity of Gelsil Radiation and Severe Environment Sensitivity of Gelsil Multicomponent and Gel-Derived composites Effects of Multicomponent Species and Multiphase on Processing-Properties Relationships and Effect of Sample dimensions on Reliability.
