    Abstract: Process for the phase transformation of substances and mixtures of substances, in which the substance or the mixture of substances is introduced into a plasma reactor, the substance or the mixture of substances is converted into the higher-energy phase and the product is removed in gaseous form from the plasma reactor. The process can be used for the sublimation of metal salts, metal nitrates and/or metal alkoxides and other vaporizable metal-organic compounds.

    Abstract: Method for the homogenisation of nanoscale powders, in which mixtures of nanoscale powders having the same or different chemical composition and/or structure and in solid form are introduced in the presence of a regulable gas stream into a vessel, the gas stream being adjusted so that the nanoscale powders remain in suspension and are thoroughly mixed.

    Abstract: A mixed silicon-aluminum oxide powder, produced by flame hydrolysis and having an amorphous structure with primary particles containing nano-crystallites, is new. A mixed silicon-aluminum oxide powder, having the composition 1-99.999 wt.% Al2O3 and balance SiO2 and produced by flame hydrolysis, has an amorphous structure (as shown by x-ray diffraction), consists of co-grown primary particles containing crystallites of 1-200 nm size and has a specific surface of 5-300 m /g. An Independent claim is also included for production of the mixed oxide by evaporating silicon and aluminum halides in a specific ratio, uniformly mixing with a carrier gas of air, oxygen and hydrogen, combusting the mixture in a burner and, after separating solids from the gas phase, removing any halide residues adhering to the product by treating with moist air at elevated temperatu
