Fluoride Glasses from Sol Gels.

Abstract

The use of sol-gel coatings to strengthen oxide glasses has been demonstrated for the case of fused silica. Increases in strength to as much as 2.2 times the strength of uncoated glass have been obtained. The strengthening does not involve the annealing of surface microcracks, but rather the filling-in of such flaws. The strengthening does not depend on coating thickness over the range 2000-10000 Angstroms, but does depend significantly upon the state of hydrolysis of the substrate surface.
