  • US Patent:
    6517629, Feb 11, 2003
  • Filed:
    Feb 5, 2001
  • Appl. No.:
    09/777834
  • Inventors:
    Stephen P. Kinniard - Ellicott City MD
  • Assignee:
    Millennium Inorganic Chemicals, Inc. - Hunt Valley MD
  • International Classification:
    C09C 136
  • US Classification:
    106437, 106442, 106445, 106447, 423610, 423611, 423612
  • Abstract:
    The present invention provides a process for generating titanium dioxide pigments that have reduced moisture retention. By leaching oxidizer discharge and removing alumina containing compounds, one is able to generate a low volatile pigmentary bases. These low volatile pigmentary bases may be processed into finished low volatile pigments that may be combined with polymers to form polymer matrices. These pigments may be incorporated into polymer matrices at high temperatures without significant lacing.
  • Method For Manufacturing High Opacity, Durable Pigment

  • US Patent:
    6528568, Mar 4, 2003
  • Filed:
    Feb 23, 2001
  • Appl. No.:
    09/792457
  • Inventors:
    Stephen P. Kinniard - Ellicott City MD
    Anne Campeotto - Eaton WA
  • Assignee:
    Millennium Inorganic Chemicals, Inc. - Hunt Valley MD
  • International Classification:
    C08K 318
  • US Classification:
    524430
  • Abstract:
    The present invention relates to an improved titanium dioxide pigment that incorporate a dense silica coating and its process for manufacture. The pigment is preferably produced from a titania base from the chloride process in which the manufacturing process comprises the following steps in the order stated: (a) partial or substantial removal of salt from the oxidizer discharge; (b) addition of a dispersant; (c) milling to produce a highly dispersed, highly deagglomerated slurry, followed by dense silica surface treatment. Pigments prepared using the inventive process exhibit optics equivalent to high gloss, high opacity pigments and maintain the durability of the more conventional dense silica treated pigments.
  • Photocatalytic Rutile Titanium Dioxide

  • US Patent:
    7521039, Apr 21, 2009
  • Filed:
    Nov 8, 2002
  • Appl. No.:
    10/291104
  • Inventors:

    Stephen P. Kinniard - Ellicott City MD,
  • Assignee:
    Millennium Inorganic Chemicals, Inc. - Hunt Valley MD
  • International Classification:
    C01G 23/047
  • US Classification:
    423659, 423610, 502350, 501 11, 501 94, 106436
  • Abstract:
    The present invention is directed to photocatalytically active rutile titanium dioxide. The photocatalytically active rutile titanium dioxide of the present invention demonstrates enhanced activity in the visible light spectrum. It may be produced by neutralizing rutile seed to a higher pH than that at which it has traditionally been neutralized prior to washing and thermally treating the seed.

  • US Patent:
    2010017, Jul 8, 2010
  • Filed:
    Mar 17, 2010
  • Appl. No.:
    12/725798
  • Inventors:
    Stephen P. Kinniard - Ellicott City MD,
  • International Classification:
    C01G 23/047
  • US Classification:
    423610
  • Abstract:
    A method for preparing agglomerates of a metal oxide by mixing metal oxide particles with a non-aqueous liquid to form a slurry, and then drying the slurry.
