  • Antimony-doped tin oxide powder and method of producing the same
    Patent number: 9513408
    Abstract: This antimony-doped tin oxide powder is an antimony-doped tin oxide powder characterized by: (A) including at least three kinds of ions selected from the group consisting of Sn2+, Sn4+, Sb3+ and Sb5+; (B) having a ratio of average Sn ionic radius to average Sb ionic radius of 1:(0.96 to 1.04); and (C) having an Sb content of 5 to 25 moles relative to a total of 100 moles of Sb and Sn, wherein the average Sn ionic radius is the average of ionic radii of Sn2+ and Sn4+, while the average Sb ionic radius is the average of ionic radii of Sb3+ and Sb5+.

  • Stable anatase titanium dioxide and process for preparing the same
    Patent number: 6113873
    Abstract: To hydrous titanium dioxide obtained by hydrolysis of titanium sulfate was added a predetermined amount of a water-soluble aluminum compound and/or a water-soluble zinc compound, the mixture is calcined, and a suitable amount of aluminum and/or zinc is introduced into the crystals to make up the crystal defects of anatase-type titanium dioxide, so that it has increased stability and excellent color stability.
