Superinsulating silica aerogel with high stiffness and density |
| abstract |
A method of producing a silica aerogel material in granulate or powder form, comprises the steps of:a) preparing a silicon oxide gel in a solvent selected from organic solvents, water, and mixtures thereof;b) triggering of the gelation of the sol by adding a gelation triggering agent, thereby forming a gel having an initial SiOequivalent concentration of 3 to 13 % by weight;c) subjecting the gel to an aging process for a predetermined aging time (t), thereby forming an aged gel;d) subjecting the aged gel obtained in step c) to a hydrophobization step;e) removing the solvent mixture by subcritical drying, thereby forming the aerogel material.The predetermined aging time (t) is selected such that the aerogel material has a bulk aerogel density (ρ) in the range of 1.15 to 3 times a limiting aerogel density (ρ) obtainable in the limit of long aging times. The method allows production of a silica aerogel material in granulate or powder form with low thermal conductivity in combination with good mechanical stiffness. |
