Abstract: There is prepared pyrogenically produced silicon dioxide-mixed oxide having a BET surface area of 50 to 400 m2/g which contains as a constituent of the mixed oxide: 0.01 to 10 weight % zirconium dioxide or 0.01 to 10 weight % iron oxide (ferric oxide) or 0.01 to 9.9 weight % titanium dioxide. Because of the doping with the foreign oxide the silicon dioxide-mixed oxide is more temperature stable than the undoped silicon dioxide. The product can be used as thermal insulation either as unpressed material in free bulk form or as a compacted mixture.

Abstract: The invention relates to monoclinic zirconium oxide having an SiO2 content of less than 1% by weight, which is characterised by dendrite-shaped particles having a mean grain size (d50 value) in the range from 0.5 mu m to 3.0 mu m and a specific surface area (BET) in the range from 3 to 15 m /g. The zirconium oxide is prepared by thermal cracking of zirconium silicate in a high-frequency or medium-frequency inductive fusion furnace with a sinter crust crucible, quenching of the melt by blowing air onto a melt jet and/or spraying the latter with water and leaching the thermally cracked zirconium silicate with concentrated alkali metal hydroxide solution at 100 to 200 DEG C. The zirconium oxides according to the invention is distinguished from prior zirconium oxide by its improved suitability for the production of zirconium silicate colouring materials of the host lattice and inclusion types - pigments of higher colour intensity are obtained.

Abstract: The invention relates to the preparation of cyclic N,N,N'- and N,N,N',N'-substituted organyloxysilyl-functional silanes by reaction of an aminopropylsilane with carbon disulphide and heating the resulting dithiocarbamate and N,N',N'- and N,N,N',N'-substituted cyclic thioureas which can be prepared in this way.
