    摘要: A method and a device for producing aerosols highly charged with liquid phase and with small droplets by using ultrasonic transmitters in which an ultrasonic transmitter oscillates in a plane parallel to, or in an inclined plane of 1.degree. to 20.degree. relative to, the surface level of the liquid. When several transmitters are used in a compact unit, each transmitter is seated in a recess and each individual transmitter oscillates in a plane parallel to, or in a plane inclined at 1.degree. to 20.degree. relative to, the plane of the surface level of the liquid. The aerosols can be used as raw material for pyrolysis, coating, the doping of substances and in medicine.

    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).
