使用溶胶-凝胶涂层来强化氧化物玻璃已被证明用于熔融石英的情况。强度增加到未涂覆玻璃强度的2.2倍。强化不涉及表面微裂纹的退火，而是这种缺陷的填充。在2000-10000 μ m范围内，强化不取决于涂层厚度，但明显取决于基材表面的水解状态。
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 tiimes 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 Å, but does depend significantly upon the state of hydrolysis of the substrate surface.
