Abstract: The novel feature in articles of 0.1-0.4 g/cm density contg. silica-aerogel particles (I) of ave. dia. (dm) 0.001-8 mm bonded together by an (in)org. binder (II) is that (II) contains layered silicates and/or clay minerals. Claimed mfr. is mixing or coating (I) with an aq. suspension contg. (II) plus layered silicates and/or clay minerals, followed by hardening in a mould.

Abstract: Gels for thermotropic sheets are claimed which are obtd. by light-radiation of a mixt. comprising (A) a non-crosslinked polymer (pref. 5-40 wt.%); (B) a radically-polymerisable monomer (pref. 1-30 wt.%); and (C) water and/or an org. solvent (pref. 30-94 wt.%). Pref. a photoinitiator is opt. also present. Polymer (A) has transparency changes in a 10 wt.% aq. and/or org. solvent soln. and is poly-N-vinylcaprolactam, a copolymer contg. at least 20 wt.% N-vinylcaprolactam, or a polyvinylether. Monomer (B) forms a 3-D network on light-irradiation and ether does not have thermotropic properties of the type specified above or has such properties at at least 20 degrees C above the switching region for polymer (A). (C) is water.

Abstract: Shaped part based on supercritically dried silica aerogel parts in the form of spherical particles having diameters of from 0.1 to 10 mm or of sheet-like pieces having thicknesses of from 2 to 30 mm and diameters of from 1 to 5 cm, characterized in that the formed part is produced by pressing at temperatures in the range from 500 to 1000 DEG C and pressures of from 0.5 to 10 bar, under a protective gas such as nitrogen, if required, and without the addition of binders.

Abstract: The material is obtainable by a) reacting an aqueous dispersion of waterglass and a pigment with a strong acid and/or waterglass with a pigment-containing strong acid to give a pigment-containing silica hydrogel, the pigment being characterised in that it scatters, absorbs or reflects infrared radiation of wavelength 3 - 10 mu m, b) substantially freeing the pigment-containing silica hydrogel thus obtained from ionic constituents by washing out with water, c) displacing the water present in the hydrogel by means of a low- boiling liquid which is inert to the pigment-containing silica gel, d) heating the liquid-containing silica gel thus obtained with complete covering with the liquid to supercritical conditions and e) subsequently removing the liquid from the solid by flash evaporation at supercritical temperature.

Abstract: A solar radiation collector, which is flowed through and cooled by a gaseous medium, consisting of a number of porous absorber bodies absorbing the solar radiation, a light-permeable cover plate or foil arranged on the sun side in front of these absorber bodies, and an insulation arranged on all sides around these absorber bodies, the absorber bodies (4) being arranged one behind another and inclined in relation to the cover plate (5) and a gaseous medium flowing through the absorber bodies one after another in in each case the entire surface.

Abstract: Described is a process for preparing polymer-enrobed pigment particles, which comprises mixing in the presence of finely dispersed pigment particles a solution of a polymer in a first solvent with a second solvent in which the polymer is substantially insoluble. The pigment particle can be specifically modified by judicious selection of the polymer.
