    摘要： Pyrogenically produced aluminum oxide, in which the BET specific surface area is greater than 115 m2/g and the Sears index is over 8 ml/2 g and the dibutyl phthalate absorption as a powder measured with a 16 g weighed portion is not measurable, is produced by means of flame oxidation or preferably flame hydrolysis, whereby a vaporizable aluminum compound is used as starting material. The aluminum oxide can be used as an ink-absorbing substance in inkjet media and also as a filler, as a substrate, as a catalytically active substance, as a starting material for the production of dispersions, as a polishing material (CMP applications), as a ceramic raw material, in the electronics industry, in the cosmetics industry, as an additive in the silicone and rubber industry, to adjust the rheology of liquid systems, as a heat stabilizer, in the paint industry.

    摘要： A silicon-aluminum mixed oxide produced by flame hydrolysis and having a composition of from 1 to 99.999 wt. % Al2O3, the remainder being SiO2, which mixed oxide exhibits an amorphous structure in the X-ray diffraction pattern and consists of intergrown primary particles, and in these primary particles crystallites are present. These crystallites having sizes of between one and 200 namometers and the specific surface of the powder being between 5 and 300 m2/g. These products are produced by a process wherein silicon halide and aluminum halide are vaporized in a particular ratio to one another and are homogeneously mixed with air, oxygen and hydrogen in a mixing unit by means of any carrier gas, this mixture undergoes combustion in a burner of known construction and, after the separation of the solids from the vapour phase, any traces of halide possibly adhering to the product are separated off in a further processing step by means of moist air at elevated temperature. The silicon-aluminum mixed oxide produced by flame hydrolysis are used in the form of dispersions for polishing, in particular in the electronics industry (CMP).
