Summary

Optimum metal-organic precursors and solvents critical to formation of strong chemical bonds during gelation and aging are described for the 20 mol% Na2O-80 mol% SiO2 sol-gel system. The use of drying control chemical additives (DCCA's) to prevent cracking of sol-gel monoliths is described.
