Thesis submitted to Paris. Universite. Study of the texture of two types of silica gels, the xerogels and the aerogels, shows that the latter evolve differently on heating. This is due to a microstructure which depends upon the preparation conditions. The state of the water of composition of these gels has been determined. A mechanism has been proposed for the adsorption of formic acid on two types of gel, thereby explaining the differences in specificity of the two solids in the decomposition reaction of the acid.
