Abstract: The invention provides an aerogel-concrete mixture, a high-performance aerogel concrete obtained therefrom, and a method for production thereof. The problem addressed by the present application is that of providing pressure-resistant but not very thermally conductive concretes, precast concrete components, screeds, screeds for precast components, (glassfibre-) reinforced concrete, fire protection panels, construction elements for thermal partition and blocks. The aerogel-concrete mixture contains: 10% to 85% by volume/m3 of aerogel pellets having a grain size in the range from 0.01 to 4 mm, 100 to 900 kg/m3 of inorganic hydraulic binder, 10% to 40% by weight based on the binder content of at least one silica gel suspension, 1% to 5% by weight based on the binder content of at least one plasticizer, 0.2% to 1% by weight based on the binder content of at least one stabilizer and 0% to 60% by volume/m3 of at least one lightweight aggregate.

Abstract: The invention relates to a method for producing an aerogel that contains a filler and has an extremely low thermal conductivity. The aerogel moulded body contains an inorganic filler with a thermal conductivity of up to 0.5 Wm?1K?1.

Abstract: The invention relates to a monotectic aluminium plain bearing alloy, comprising 5 to 20 wt. % bismuth, 3 to 20 wt. % zinc, 1 to 4 wt. % copper and additionally several of the components manganese, vanadium, niobium, nickel, molybdenum, cobalt, iron, tungsten, chromium, silver, calcium, scandium, cerium, beryllium, antimony, boron, titanium, carbon and zirconium in amounts up to 5 wt. % and aluminium to make 100 wt. %, produced by strip casting and during the subsequent production process for plain bearings, after rolling or roll-bonding, subjected to a heat treatment at ca. 270 to 400° C. Long bismuth particles or sheets, produced by rolling or roll-bonding can thus be recoagulated to give finely-distributed spherical drops with a size in the 20 ?m range and smaller.

Abstract: The present application relates to a porous composite material consisting of a metal matrix with embedded nano-structured materials.
