Abstract:
A doped, pyrogenic oxide of at least one of a metal, a non-metal and a metalloid, produced by a process comprising:providing an aerosol comprised of, at least one of a solution and a suspension of a substance to be doped selected from the group consisting of a metal salt, a non-metal salt, a metalloid salt, and mixtures thereof, and at least one of a solution and a suspension of a doping substance selected from the group consisting of a metal salt, a non-metal salt, a metalloid salt, and mixtures thereof; mixing the aerosol with a combustible gas stream to create a combustible gas stream mixture; reacting the gas stream mixture in a flame; and separating the resulting doped, pyrogenic oxide from the gas stream mixture.
