Die Erfindung betrifft eine Zusammensetzung, die 30 bis 95 Vol.-% Aerogel-Partikel und mindestens ein wässriges Bindemittel enthält, wobei der Teilchendurchmesser der Aerogel-Partikel kleiner als 0,5 mm ist und die Aerogel-Partikel vorzugsweise hydrophobe Oberflächengruppen aufweisen, ein Verfahren zu ihrer Herstellung sowie ihre Verwendung. The invention concerns a composition containing 30-95 % by volume aerogel particles and at least one aqueous binder. The aerogel particles are less than 0.5 mm in diameter and are preferably provided with hydrophobic surface groups. The invention also concerns a method of producing said particles and the use thereof. L'invention concerne une composition renfermant 30 à 95 % en volume de particules d'aérogel et au moins un liant aqueux, dans laquelle les particules d'aérogel sont d'un diamètre inférieur à 0,5 mm et présentent, de préférence, des groupes superficiels hydrophobes. L'invention concerne également un procédé de fabrication d'une telle composition, ainsi que son utilisation.
