    Abstract: A process for the drying of inorganic hydrogels obtained from readily hydrolyzable compounds of the elements Al, Si, Ti, B, La, Zr, Cr, Sn, Th or Mg, and organic hydrogels based on gelatine, albumin or agar agar, from CO2, to give aerogels is easy to carry out industrially, and drying can be effected at from room temperature to 90 DEG C. The resulting aerogels are transparent and have a low bulk density and low thermal conductivity. The aerogels can be used as packing materials for liquid chromatography, as catalyst carriers, as substrates for enzymes and as adsorbents.

    Abstract: Process for producing insulating panes, comprising at least two panes which are arranged in parallel at a distance of from 5 to 50 mm, are approximately of the same size and are connected at the edges such that they are airtight or gastight in a manner known per se. Loose air-impermeable or gas-impermeable sheets connected to the seals at the pane edges in an airtight or gastight manner rest on the inner sides of the panes, the space between the sheets is sealed with small aerogel balls, said space is then closed off in a fully airtight or gastight manner and is subsequently evacuated to the desired extent by means of a suitable device (tube), and air or an inert gas at normal pressure is fed in at the same time between the sheets and the panes through one or more openings or tubes. The opening at the evacuating point is then closed off in a vacuum-tight manner, while the openings between the panes and sheets are either closed off or, if appropriate, remain connected to the outer air via a drying agent.
