Abstract:
A process of producing a doped, pyrogenic oxide which is doped using an aerosol, the process comprising:providing an aerosol comprised of at least one of a solution and a suspension of adoping substance selected from the group consisting of a metal salt, a non-metal salt, a metalloid salt, and a mixture thereof;conducting the aerosol through a heating zone by means of a carrier gas stream to thereby evaporate at least a portion of the aerosol;mixing the evaporated aerosol in the carrier gas stream with a combustible gas stream which comprises at least one of an evaporated solution and an evaporated suspension of a substance to be doped selected from the group consisting of a metal salt, a non-metal salt, a metalloid salt, and a mixture thereof, to thereby create a combustible gas stream mixture;reacting the combustible gas stream mixture in a flame; andseparating the resulting doped, pyrogenic oxide from the reacted gas stream mixture.
