Patent ID: 7582276

Claim:
A method for producing a nanoscale rutile or oxide, the method comprising the steps of: a) adding an alcoholic solution to a first alcoholate containing a rutile or oxide to be extracted, thereby introducing water and acid, to obtain a first suspension having an amorphous material compound, the rutile or oxide selected from the group consisting of titanium dioxide, barium titanate, zirconium dioxide, SnO 2 , ATO, ITO, Y 2 O 3 , In 2 O 3 , CeO 2 , ZnO, BaO, CaO and MgO; b) isolating said amorphous material compound through removal of solvents; c) redispersing, following step b), said amorphous material compound in an aqueous solution which is adjusted to an acidic pH value using acid or in said alcoholic, water, and acid solution of step a) to obtain a second suspension; d) adding, following step c), at least one of a water soluble tin compound, a water soluble sodium compound, a tin salt, a sodium salt, an ammonium compound or a chemically equivalent compound to said redispersed amorphous material compound; and e) crystallizing the nanoscale rutile or oxide in a hydro-thermally or a thermally supported manner.
