Abstract: Process for the production of monoliths of glass by means of the sol-gel process, comprising the following steps:

a) dispersion in water of an oxide prepared by the pyrogenic route,
b) hydrolysis of an alkoxide in aqueous solution to form a hydrolysate,
c) mixing of the hydrolysate of the alkoxide with the oxide prepared by the pyrogenic route to form a colloidal sol,
d) optional removal of coarse contents from the colloidal sol,
e) gelling of the colloidal sol in a mould,
f) replacement of the water contained in the resulting aerogel by an organic solvent,
g) drying of the aerogel,
h) heat treatment of the dried aerogel.
