SiO2 aerogels containing carbon particles and their preparation

摘要

SiO2 aerogels containing carbon particles are obtainable by heating a) organically modified SiO2 aerogels in the presence of at least one pyrolyzable hydrocarbon gas and/or at least one inert gas or b) organically unmodified SiO2 aerogels in the presence of at least one pyrolyzable hydrocarbon gas and in the presence or absence of inert gases to 600 DEG -1300 DEG C.
