Physical Review Letters, 1991
The structure of silica hydrogels has been studied by elastic light scattering. Like colloidal silica gels and neutrally catalyzed aerogels, these gels show mass fractal behavior at length scales below a crossover length \ensuremath{\xi} and scatter like a spatially random distribution of fractal objects for length scales g\ensuremath{\xi}.

Sol-gel techniques can be used to produce two new types of optical silicas, termed Type V for the full density material and Type VI for the optically transparent porous material. This paper summarizes the processing differences between these six types of commercial silicas.

Silica Aerogel: Synthesis, Characterization, Applications, and Recent Advancements
Particle & Particle Systems Characterization, 2023Silica aerogels have drawn considerable attention due to their low density (almost 95% of the total volume is composed of air), hydrophobicity, optical transparency, low conductivity of heat, and large surface to volume ratio.

The processing and properties of Types I and II fused quartz optics and Types III and IV synthetic fused silica optics are compared with new organometallic sol-gel derived (Types V and VI) gel-silica optics. Type V gel-silica has excellent transmission from 165 nm to 4200 nm with no OH absorption peaks.
