Abstract
Described is a method for the production of pure or mixed metal oxides, wherein at least one metal precursor that is a metal carboxylate with a mean carbon value per carboxylate group of at least 3, e.g. the 2-ethyl hexanoic acid salt, is formed into droplets and e.g. flame oxidized. The method is performed at viscosities prior to droplet formation of usually less than 40 mPa s, obtained by heating and/or addition of one or more low viscosity solvents with adequately high enthalpy.
