Oxide gels are amorphous and porous materials. The main recent challenge in the investigations of these materials is to reduce and even eliminate their porosity while keeping their starting amorphous nature. In this paper, we describe how, during the last few years, the understanding of both their s
The linear thermal expansion coefficient, a, has been measured from 2 to 32 K and from 55 to 90 K for a machineable glass-ceramic, an "ultra-low expansion" titanium silicate glass (Coming ULE), and ceramic glasses (Cer-Vit and Zerodur), and for glassy carbon, a is negative for the ultra-low expansio
